Pros:
Top of the line sensor
Lightweight
Perfect shape for me (shaped like deathadder but with a place to actually put your thumb, brilliant)

Cons:
Feels cheap
Buttons feel very loose, wobble around a lot, not very tactile
DPI button is on the top (every mouse company should take cues from zowie on this)
Quality control issues (first one was defective)

If you can deal with the cons, this is a lovely mouse. There is no other mouse that is as lightweight and "no-frills" as this.

Best mouse I've ever owned by a long shot. I have tried using other mouse since but the optical sensor on this one is the most accurate that I've ever had. I can legitimately feel the difference in accuracy when trying to use other mice and nothing really compares. A great alternative to the Razer Death Adder and will last for more than just a year or so...

I have been a long time user of the legendary Logitech mx518 mouse, and decided it was about time for an upgrade. After doing some browsing, I came across the CM Storm line of products. Truth be told, I found a good deal on the CM Storm Inferno first. To make a long story short, the Inferno was a cool mouse but very uncomfortable for me. Being a claw grip user, I needed something that fit my style - enter the Spawn. I ordered up one of these bad boys, returned the Inferno and the rest was history. It felt immediately comfortable for my claw/fingertip style grip, and the only thing that took a bit of getting used to was the higher DPI. When I say higher DPI, I mean the 1800 setting. I NEVER use the 3500 setting as it is just waaay too much, as on my old mx518 I would use around 1400-1500 tops. Once adapted, I immediately started noticing improvements in my game. Most notably, I used to be horrible with the "rail gun" in Quake multi-player games. If you are familiar with Quake, you know the rail gun to be a high precision, sniper type shot that requires dead on accuracy. Before writing this review, I just completely owned a server, with 14 impressive medals for what they consider to be impressive shots. I was never this accurate with the Logitech mx518 people, so this is tangible proof the Spawn can improve your game in FPS! The tracking quality with the latest firmware is top notch and feels smooth and deadly accurate. I loved my 518 folks, but it is now retired and I am a fan of the Spawn. You may be wondering, with such a glowing review, why the 4 stars instead of 5? Well, this mouses biggest shortcoming is its lack of custom DPI settings. You can switch between 800, 1800 and 3500 - period. While the 1800 and 800 settings have proven fine for me (once adapted), I would certainly like to have the option to set something between the two, or to even go lower than 800. This day and age, there is no excuse for not allowing such a feature in a mid-range gaming mouse. Even my aging 518 had it! Anyway, with that aside, this mouse is making me a believer more every day. The software is simple, straightforward and easy to use and allows for macros. You can also set your polling rate from 125hz to 1000hz. I prefer mine on 500hz.

If you have an aging mouse, use a claw/fingertip grip and might be looking for a new answer in game - the Spawn may very well be that answer. IF you're a palm gripper i'd skip it, because it is fairly short and a bit on the wider side to specifically fit the claw style. If you do get it, just be sure to flash it to the latest firmware to improve your LOD (lift off distance) and get the most out of it. Its accurate, smooth, comfortable and deadly in the right hands. My night and day improvement with the rail gun in Quake is proof enough for me!

To sum it up:

PROS
- Very comfortable for the claw/fingertip grip
- Highly accurate and precise sensor
- Smooth efficiency
- Top notch buttons and button placement
- Simple and solid software
- Custom polling rate settings via software

CONS
- No customizable DPI settings beyond the three presets: 800, 1800, 3500
- No braided cable
- Stock firmware and LOD is bad / firmware must be updated for proper performance

Amazing mouse. If you are looking for a simple, light and comfortable mouse for hours of computing at work or at home  then this is the one.

I use a 10 port KVM switch and it is too hard to find a mouse that is compatible with the KVM switch. This  one just works!! not to mention it is light (weight), fits my large hands very comfortably and the mouse clicks are just loud enough to give you a confirmation of the click but not loud enough to wake up your office cubicle neighbor.

Highly recommend it.

I am a previous Razer Naga owner, having kept around the original naga (blue lights) for a few years now.  Unfortunately, the optical sensor in the mouse began to die and it would no longer track properly.  Enter my exhaustive search for a new MMO mouse.

At first, I was hesitant about this due to having no previous exposure to the brand, and not being immediately fond of the angled format of the 12 side buttons.  Let me start by saying, this mouse is absolutely fantastic, and handles so much better than I *ever* remember my Naga performing.  It's great having the profiles stored on the mouse, and no longer be tethered to a machine that has Synapse installed, the DPI adjusting buttons are easy to press, but out of the way enough that I would never accidentally hit them, and the management software was very straight-forward.

This being said, there are a few issues I have with the mouse.  The entirety of the mouse has a similar finish as to the sides of the Naga.  This smooth plastic has an issue with collecting sweat and skin from play, and needs to be cleaned periodically.  The other problem is the lack of ability to adjust the color of the scroll wheel light.  This coloring is tied to the specific profiles, which does help to distinguish between them, but it limits the color options of the rest of the mouse when you are trying to make them compliment each other.  As for the 12 side buttons, I am still adjusting to the new zig-zag pattern, rather than the convex bow that I am used to, so the third row (7-9) are a challenge for me to press.

One word of warning when shopping for a mouse-pad for this product.  The laser sensor in this is incredibly sensitive, which is easily represented when you play on high-DPI (I've been loving spending time upwards of 12,000).  Due to this, the mouse will not track well on cloth pads, or even on plain printer paper.  However, I've had it work perfectly on the top of a wooden dresser, the back of a glossy magazine, and the metal of my laptop.  In the end, any smooth, solid surface should track amazingly well and make for a satisfying purchase.  Don't make my mistake and purchase the SteelSeries QcK shown in "Also bought with."  The mousepad is great, but the cloth will not work with this mouse!

I wanted a simple mouse to plug into my laptop and didn't want to worry about batteries or worrying about keeping track of a tiny wireless adapter. This is perfect, lightweight, precise, great price.

Finally found a nice lightweight slim mouse for finger grip. The cursor is precise, great for gaming and art work.

I purchased the 'asian' pro gamer edition Salmosa, model number RZ01-0022, which is smaller than the normal version pictured here. This edition does away with the polling switch on the bottom, leaving only a 800/1800dpi selector. I was looking for a small, lightweight mouse for fingertip RTS gaming, and the forums seemed to really recommend the Salmosa.

The moment I started using it, it seemed to fit the bill. At 57 grams, it's one of the lightest mice I've used. (The g9x is about 110 g unloaded and the anywhere mouse comes in at 138 g) My hands are probably smaller than average, but this Salmosa even feels pretty small for me.

However, the simplicity of the mouse means that it is relegated to a dedicated gaming mouse. For this purpose, it's great--the left and right click buttons have decent tactile response, as does the scroll wheel. The edges of the click buttons are wavy to form an ergonomic groove for the index and middle fingers. This makes it precisely suited for fingertip gripping. The sensitivity switch is almost perfect for quickly transitioning from Brood War and Starcraft 2, if necessary. There's no extraneous buttons or hyper scroll wheel for you to accidentally press in the heat of battle.

For everyday use though, I find the Salmosa lacking. It doesn't offer the quick sensitivity control of the g9x for photoshop work, and it can't track on glass like the anywhere mouse. It's actually TOO light at times, because sometimes it's good to feel the weight of something moving around. It's also too small for 3 finger usage: resting my middle finger on the scroll wheel and using the ring finger for right clicks resulted in an awkward, cramped hand position. I I ended up getting the g9x for about $40, which is only $10 more than I got the Salmosa for. It's just got so much more functionality, easily making it my all-purpose, everyday mouse.

My mouse also started picking up a lot of dust around the edge of every single sticker on the bottom. This has never happened with any of my other mice, and it's actually beginning to give me tracking glitches. If you've ever had a Logitech mouse break down or malfunction, you can be assured that they'll take care of you with a new replacement for free under warranty--almost no questions asked. Razer isn't nearly as generous.

In short, the Salmosa is a simple, small, lightweight mouse that's okay for gaming. But that's exactly what you get--a 2 button, scroll mouse. I really wondered where my money went, and how it could have gone elsewhere.

I loved my old DeathAdder and I was super happy to get my new one as quick as I did. I've had no problems with it, the old was was wearing out because of how long I had it and how much I used it.

I've had six copies of the same mouse,&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Creative-Fatal1ty-2020-Laser-Gaming-Mouse-7300000000422/dp/B000FEHVWG/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Creative Fatal1ty 2020 Laser Gaming Mouse ( 7300000000422 )</a>&nbsp;since 2004 which attributed to my clawish fingertip grip of 3 fingers flat up top, wrist off the table, claw thumb and relaxed pinkie. Unfortunately the 2020 had a lot of issues with the switches and the LMB would go out after a couple of months of CS:S. I was on my last copy and got this mouse as a gift.

Even though it broke frequently, I've always been happy with my previous mouse. They just don't make it nowadays and I felt that needed a little higher DPI for running 5760x1080.

I like peripherals a lot and I've purchased too many other mice designs from Logitech, Razer, Microsoft, and most recently the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Cyborg-Gaming-Mouse-for-PC/dp/B003CP0BHW/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Cyborg Gaming Mouse for PC</a>. Nothing fit right or their tracking was off or the buttons were too far forward. Until now, the old 2020 mouse just kept winning me over all other products.

Regardless of how many adjustments the Cyborg mouse had it did not have the odd grip that I was looking for. This mouse has no special moving parts. Nothing to worry about or lose other than the weights.

Physical properties and tracking are the two main things I look for in a mouse.

The Corsair M60 has about the same shape as my previous mouse, less the third mouse button on the right and the palm being a little farther back. It's still about the angle in how I hold the mouse. There is just enough comfortable space for my right ring finger to sit in the far right groove without impeding my right click.

Speaking of which, I'm very pleased about the definite and easy mouse clicks from high up on the mouse with solid but little effort. Middle mouse button is a little stiffer than LMB and RMB and it's wheel movement feels intentional.

The laser is great and tracks my arm and wrist physics precisely with zero travelling. It moves precisely where I want it to. 1 inch on my plain white tile turns my character the same every time I move across it. It doesn't get any better. I've experienced zero skips and lag. The cabling and plug are sturdy. The weights are can be adjusted very easily, however I wish there were more places to place them.

The sniper button is too far forward for my style and I've opted to use the back button (MOUSE4) as my fast weapon switch. It clicks very fast with a quick thumb swipe up. I do not use the sniper button's functionality to slow down dpi. I did not have any driver issues with this feature.

The software seems OK, nothing too great or too bad about it. Your standard features as in DPI setting, independent XY, polling rate, lift height and command assignment. The only thing I wish this software had was the ability to change the mouse angle... but that's 1% of what I look for in a mouse. The surface quality indicator is a nice touch.

This mouse feels very solid and the switches feel durable. I'd buy six of these in a heartbeat, but I doubt that I will need to.

Win 7 64 bit. Downloaded 12/22/11 drivers. Not a single hiccup and plays very well. Seemed just as good without the drivers/software.

My top personal favorite gaming mouse, definitely a comfortable mouse and great for eSports, and regular internet browsing all alike. RGB is definitely great, but isn't the primary feature for me, the sharp and accurate sensor was the main reason I brought it, am definitely impressed and recommend this to anyone who wants a great mouse.

This mouse is slim and very lightweight. I am using it with an ultrabook and wanted a mouse that would not be too bulky in a bag. This is the perfect mouse for portability and it goes great wiht my ultrabook. I would reccomend this product to anyone. It is responsive and goes into a sleep mode when it is not being used to save energy. The USB is tiny, so it does not stick out of my ultrabook like my last mouse. Such a great mouse. Oh, and it is comfortable to use. I have trouble with my wrists, so comfort is important. This mouse has everything!

We're a very avid gaming household who tend to buy and cycle through a lot of different mice, so we're always on the lookout to try something new. I generally use a standard 5 to 6 button mouse for most games but for MMO's and FPS' I prefer a mouse with more buttons to better customize my play style. When I saw this mouse I thought it would be the perfect item to test out and review. Here are my thoughts on the SteelSeries Sensei Wireless Laser Gaming Mouse;

Pros

+ Textured rubber sides help keep your hand on the mouse even during the most frantic gameplay.

+ Non-sweat surface is smooth while offering a good grip and is easy to clean.

+ Steel Series logo and scroll wheel LED's illuminate a nice soft multicolor glow without heating up. They also have multiple levels of brightness and different lighting effects to choose from.

+ Perfect mouse size makes it easily usable by both small and large hand types.

+ Mouse lays flat in the charging base creating a perfect connection.

+ Instantly adjust your DPI with the click of a button.

+ Illuminated charging base notifies you when the mouse is beginning to lose power.

+ Comfortable ergonomic design usable by both left and right handers.

+ Usable as both wired and wireless.

+ Quick and easy installation.

+ Smooth glide movement.

+ Lightweight construction.

+ 8 programmable buttons.

+ Quiet scroll wheel.

+ Sleek design and simple look.

Cons

- Mouse uses Steelseries Engine 3.  If you have another Steelseries device that uses Steelseries Engine 2 it's incompatible with Engine 3 which forces you to run two different programs to customize your key binds and lighting effects.  For example I have the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/SteelSeries-Apex-Gaming-Keyboard/dp/B00DQ5RGOY/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">SteelSeries Apex Gaming Keyboard</a>&nbsp;with which I ran into this problem.

- Non-standard USB plug on the head of the mouse so you can't just use any random USB cord.

- Quite expensive with a list price of $159.99 and the overall construction feels a little cheap.

- For a FPS player this mouse is great, but for an avid MMO player I feel it lacks buttons compared to many other gaming mice on the market.

- No left-right click on the scroll wheel.

- May be a bit too light for some users.

The "SteelSeries Sensei Wireless Laser Gaming Mouse" is a solid and well designed mouse aimed towards the gamer but still usable by all. I actually began using this mouse at work as it has just the right amount buttons for my daily desk routine. Overall, the mouse has a comfortable ergonomic shape, numerous buttons and incredible accuracy. However, I do feel that this gaming mouse is better suited for the FPS player over an active MMO player due to its lack of buttons. The "SteelSeries Sensei Wireless Laser Gaming Mouse" is a respectable multi-functional gaming mouse which should please most average players while being equally functional for everyday use.  My only real gripe is the high retail.  However, if you're willing to drop the extra cash for this mouse chances are you won't be disappointed.

This mouse is everything I could ask for. I come from a long line of logitech mice and this is by far the most complete unit.

 My g700s was a great mouse and a great performer, it did often feel a bit too big/heavy after long session. It has a higher bulge up top and forces your hand to curve up and wrap around the mouse. The biggest complaint I had was the battery life, it was much too short. The only redeeming factor was the replaceable battery.

I also had the MX master and while it was a beautiful mouse, the shortcomings for my personal use were too much for me to ignore. Primarily the inability to save settings on board memory meant if you plugged it to another pc you'd have to install and set it. For those on work provided laptops who are unable to install 3rd party software won't be able to adjust settings/sensitivity. It also caps out at 2000 dpi and while that's enough for most people, I've gotten used to being around 2500-3500 depending on what I'm using.

This brings me to the g900 chaos spectrum mouse. The mouse is incredibly light, pin point accuracy, and very low resting hand position. The settings are able to be saved on the mouse itself and also offers to ability to add or remove buttons. It also adds a pretty snazzy and adjustable RGB led in the logo and the dpi indicators. I've only been using it for a couple days but I've been pleasantly surprised with all that it offers.

pros :
- ability to save profile settings on mouse
- light
- very accurate
- confortable hand position
- very nice and satisfying clicks (mouse and wheel)
- customizable (lights)

cons:
-price is a bit hard to swallow.
- would have loved a smart scroll feature like the MX master

Cool mouse. lightweight and fits my hand perfectly. It is bigger than your usual mouse but that worked out great for me.

Excellent tracking, lightweight, definitive L/R clicks, and the hump on the mouse rear -- make this an excellent mouse for my hand.  If it had a tilt wheel -- it would be nearly perfect.  I also like the placement of the thumb buttons,  They have just enough resistance to make them "not too" easy to hit while resting the edge of your thumb on them.  I've used plenty of gaming mice in my life, and this is one of the very few with high mounted thumb buttons that executes the placement/feedback perfectly.  Really a joy to use.  Highly recommended.

So far.. Amazing! I have large hands so I went with the Ec1-a and I love how simple and solid it feels and with good weight. People say that it may be similar to deathadder but I think its different, but in a good way. I love the plug and play style. The side buttons feel a little flimsy but I can't detect a review of them breaking... even if they were broke, I would still use this mouse. Hope this helps for large hand gamers... I have 9 1/2
