Phenomenal wired mouse. 2 years of use - no defects or functional issues at all.

I'd recommend this mouse to anybody. Functionally, there's nothing spectacular about it, but there's also nothing wrong with it. It's what a mouse truly should feel like; "don't fix anything that isn't broke". Though people prefer different sizes, the Abyssus's grip works well for me. Here's what I'd like to highlight:

-It is a light mouse. Lighter than the Deathadder, Mamba, and probably even the Orochi

-It has a 'medium' grip. I'm 6'0" and the base of my fingers where calluses are formed from weightlifting (sorry... no idea what that's called) rests on the top of the mouse. The middle of my palm gently touches, but does not rest on, the blue glowing part of the mouse. I have no problems with the grip.

-I think the clickiness is perfect. Some mice like the most popular Microsoft wireless mouse (forgot name) is relatively harder to click, and the Mamba is much easier to click. I don't see any problem with this mouse's clickiness - very easy to click but not too soft. The curvature of the buttons are also ergonomically pleasant for your fingers.

-Love the scroll-wheel. I don't like free scroll; I like wheels that move the page up/down in standard increments. Interestingly, this mouse's wheel started to squeak after a year for about 2 days... then it just went back to normal. I didn't do anything to it before or after.

-I use the cardboard back of a legal pad as my mouse pad - works great. Don't see a need for a mousepad unless you're a competitive gamer.

-One issue for some is that the light stays on even when your computer's in sleep mode.

My settings for non-gaming use are: 1000hz and 1800 DPI.

I've gamed a bit with this - Starcraft, Counter-Strike, Dark Souls, you name it - no problems with gaming. (I'm not a competitive gamer but I'm diamond in SC if that means anything...)

Overall: great mouse, haven't experienced any major defects. I would and have recommended this to my friends. 5/5

Excellent over all mouse, nearly 2 years later and it just now started to give me problems. Random connectivity issues with the bluetooth dropping out on multiple devices. Battery life still remains excellent.

I bought this mouse in 2011, and it's been a great the last 7 years. It feels great in your hand, and can be customized in weight, texture and shape. The unlockable scroll wheel is a feature I never thought I would use so frequently. Adjustable DPI on the mouse is great to have when you're going in-between different games frequently. Mine has recently been having some connectivity problems, but a new USB cable for $3 fixed that and it's as good as new.

The best mouse i have ever used. Period. Its so comfortable (as long as you are right handed) and all of the buttons are well sited (the only downer on this front is the scroll wheel middle click is a little too hard). I don't use the DPI switches often, so can't really comment on those.

I've been using it for nigh on 6 years now i reckon, and it still works fine. It has been battered all over (regularly dropped when I move my laptop) and has never broken once. My final point is it also looks really cool!

If you are considering it, just buy it.

I bought this in April of 2013 and this is one of the best mice i have ever used. The laser has three sensitivity settings that can be changed by the center button on top, but doesn't get in the way when using it. It has held up quality wise perfectly, never had any issues with it. I use this for general laptop use as well as all types of gaming, works like a dream.

ive had this mouse for quite some time... basically bought them when they first came out like two years ago.  YOU WILL NOT BE DISAPPOINTED. the shape takes some getting used to but thats the case with any new mouse.  The ability to fold flat is an amazing feature.  the mouse tracks accurately, much better than most.  I use it on a glossy desk and it does way better than a traditional laser mouse.

Im currently in law school and many ppl use the mousepad on their laptops because a traditional mouse is clunky and awkward to carry around.  This mouse, however, looks fancy and simple (i always get compliments on it and people always want to play with it)  and works as well as it looks.  The scroll wheel is just a flat touch surface with a tactile clicking/tapping sound when you "scroll".

When i first purchased it, my concern was that all that bending to turn on and off the mouse would mean the mouse would break within a year but i was pleasantly surprised.  The casing is a rubberized feel and overall is just designed very well.  Would def buy again if the need came up again, so far the original one is going strong!

I also like how the USB connector is a micro connector and it just magnetizes to the bottom on the mouse if you ever need to store it (i just leave it in connected to my laptop always).

I bought this mouse about a year and a half ago and I wouldn't have expected it to have held up this well for so long. It has withstood daily use of at least 3 hours a day, and it's still going strong. I have used this for an unbelievable amount of gaming and it has stuck with me for the entire ride. For the price, you will be extremely hard pressed to find something of higher quality and more reliability than this thing.

this thing has worked perfectly for over a year.

- the connection never drops. never had to reset it. (RF signal)

- no problems with the cursor/pointer. (optical, not rolling ball).

- using a non-rechargeable wireless mouse is a pain in the butt. you'll be scrambling to find batteries like I did for years (and may be screwed when you do not have any! - you'll be removing them from remote controls) when they run out.

- it holds a charge for a week or longer of HEAVY use. i routinely forget to charge it because the charge lasts so long.

This is the way it is supposed to be!

This is a top notch wired mouse. I searched high and low for a quality wired mouse, I was completely willing to spend up to $120 on one.
I view a mouse like an office chair, it as a really durable good. They are both something i will use a lot, and i want them to be durable and comfortable.
Pros:

-I like that this mouse has the weight set. I didn't think I would really use it, however it really does add to the way the mouse slides in a very beneficial way.
-The braid on the wire is really helpfully in making sure that the mouse doesn't get hung up on edges
-Buttons to increase dpi on the fly (Really do find myself using this feature *a lot*)

Cons:
-Wish the shape was a bit taller to fit into the palm of my hand. The shape of the mouse is a bit flat/ for small handed people. I am 6 ft. tall. This is something i had to settle for due to there not being a lot of options for quality wired mice.

No Opinion:
-I don't find myself using the software all that much

I didn't want to do wireless, b/c i got tired of having to search for batteries at the most inopportune gaming moments.

I had my last mouse, which was a Microsoft wireless mouse/keyboard combo for a little over 8 years. Still have them both connected to my media server.

Two years ago, I bought my first optical mouse. I instantly loved it, except the cord frequently got in my way. Recently, I decided to purchase a cordless mouse, and felt the Logitech MX700 Cordless Optical Mouse was the way to go.
Besides being cordless, optical, and a Logitech product (they hold up really well), the included rechargable batteries and charging station/wireless base attracted me to the MX700. Features I became so accustomed to on my first optical mouse -- buttons to move ahead and back one page in my web browser, and a scroll wheel -- are included, so I lost no functionality.
The MX700 includes three other buttons that some may find handy: one each to scroll up or down a page, and one to switch between active windows on your desktop. Personally, I have little use for these.
Aesthetically, it's a sleek looking device with its black and silver matte exterior. Because of the batteries, the MX700 is slightly heavier than the average mouse, but the weight difference is negligible.
I have two minor complaints about this product. First, the mouse is longer than I'm used to, so my feel for it will need to adjust. Second, it's not ambidextrous -- southpaws are out of luck on this one for now.
Unless you have two spare AA batteries, this is not a mouse you can set up in a hurry. You'll need to fully charge the included batteries before installing the mouse. I charged my mouse overnight, so I can't say approximately how long it took.
Overall, it's a great mouse, accurate to a fault, and PC and Mac compatible. (Good news for me, since I plan to switch to Mac sometime this year.)
UPDATE, 1/12/04: I installed the mouse onto my new Mac last week, and it worked straight away without installing any drivers. To use the additional buttons, though, I had to install the drivers.

This was my first 'serious' gaming mouse. I have used it pretty much daily for about 2 years now and have never once had a problem with the mouse for everyday and photoshop use. I play competitive FPS video games and have no problems with a mousepad. On hard/rough surfaces it has problems tracking, as do my other mice. I take very good care of my gear, and have never dropped the mouse, which apparently could create problems. Is it the most serious gaming mouse out there? Probably not. But it has all the features of a high end mouse that make it a 'good enough' pick for me.

I've been using this mouse for a couple of years, so I think "durable" is a good way to describe it. I also use it to control my laptop from across the room, so I feel like a wizard with a magic wand. But in reality it just has a good wireless reach.

I bought this mouse about a month ago and game pretty heavily so after having put some time into this mouse, it's time for a review. I have mostly used logitech peripherals in the past, having used my G5 until it recently died (RIP). To my knowledge, the G5 was one of the first peripherals to have a modular feature, so as ten years passed by on that mouse it's now impossible to imagine using something as simple as a death adder or naga.

Enter the Roccat Nyth.

I was initially really drawn in by the shape and dpi of the mouse, (from 1200 to 12000, quite high compared to some others currently on the market), the modular side keys were also a serious point of curiosity for me. I am largely an MMO player, so the functionality of side buttons is hugely important to me. The overall construction of both mouse and buttons seems to be high in quality, in my opinion the mouse is very ergonomic and of course the included side button sets are a huge plus, but more on that shortly.
The Nyth comes with support software for DPI control, axis sensitivity, color options, and button mapping. I was at first a little overwhelmed with exactly how in control you are with regards to exactly what this mouse is capable of. It has up to 24 functional binds per profile, and the ability to set per-game profiles which is a major plus. The standard millions of colors are present, though I find the programmed color transitions are a little jagged and as a result I simply leave it red. Once you decide what buttons to use to for your Nyth programming them is quite simple as is assigning them to a specific game.

One other side thing, for those who are fortunate enough to have access to it: You can 3D print your own buttons for this mouse if you can access a 3D printer. I have yet to try it but Roccat's site has the info.

Pros:
-Likely unparalleled in terms of sheer customization options, both on a hardware and software level.
-Software allows seamless profile transitions from game to game.
-Very comfortable to use, have not experienced any fatigue during long gaming sessions.

Cons:
-Included a set of dummy keys that in my opinion would make for the best option to use were they usuable.
-Some may have software issues.
-Ships with a default of ~1200 DPI. Leave your old mouse in while you program this one.

Final thoughts: For somebody who has used one mouse for 10 years in favor of many newer options, this hits all the right spots for me. If I could find another G5 for around the cost of this it might be a different story, but since I cannot I think I have found my next 10 year mouse.

I've had this mouse for about 2 years now. Works the same as the day I first got it. Love the design of the mouse and I love the buttons on the side of it.

This mouse has been through many hours of intense gaming and tournaments with me.

I played games like:

- World of Warcraft
- Elder Scrolls Online
- Warthunder
- World of Warships
- Elite Dangerous
- Counter Strike
- Ghost Recon Phantoms (did two tournaments for this game)
- Rainbow Six Siege

Let just say this mouse has taken a beating in the last 2 years and its tough as hell. Would definitely buy this mouse again if I need to.

I've had this mouse, in its wireless form, for the better part of a year, since having carpal tunnel surgery on my mouse hand.  It keeps my hand, wrist and arm more comfortable than any other product I've used for the last 25 years, from digital pens to graphics boards with 30 button pucks to standard mice and other ergonomic mice.  While I would prefer more robust scrolling and about three more buttons, for my normal job it works well.  It's a little tough getting used to NOT nudging your pointer with your wrist, making delicate work a little more time consuming.  In those cases, I keep a good standard optical mouse that I can use for very fine manipulation.  I have not used it, however, in about 10 months.

This rates the mouse a 5-star for me.  I only wish I could stop here.

First:  You can't click both R and L mouse buttons at the same time - it's a rocker switch.  Yes, I do this.  For some applications, this is the same as a middle button click.  And no, the click on a scroll wheel does not cut it, esp. since ...

Second: Only two buttons, not configurable, no scroll wheel.

Lastly, the buttons keep crapping out on me.

I'm actually using one different from the one I purchased.  The original, after 1 week of use, started missing button clicks.  I contacted 3M and they replaced it free of charge (and even paid for the return shipping).  The second one has lasted about 10 months with only intermittent weirdness with the buttons, occasionally requiring a second click.  Now, for the last two weeks or so, I've been double-clicking four to six times to select programs, icons, etc. and it still doesn't take.  A single click rarely works the first time, usually requiring three or four clicks to select properly.

I haven't yet determined if this is an issue with the wireless or with the physical button switch.  I do know that I'm starting to get 'nintendo thumb' - pain in my thumb joint - for having to click so madly.

Here's the thing, though - I'm going to get a wired version next.  The cost per year, even for the next 10 years, is still less than permanent nerve damage and additional surgery.  Maybe after I get a few, I'll mod them into one that more closely follows standard button configurations.

Bottom line:
 - love the shape and feel
 - would like more functionality with buttons, scroll wheel, but not a deal breaker
 - button hardware seems sub-par

I've used this mouse for the past few years. I tossed the cases and use it skinless (Dirty, I know) but it's feel, reaction and precision has served me well for several years.

I haven't had any problems with it breaking or slowing down throughout my time using it and I've used it for a variety of activities including gaming (SC2, WoW, various fps), designing (Illustrator, inDesign, Photoshop, etc.), and of course, all the various Word/email/surfing basics.

I highly recommend this for gaming AND everyday use though I probably wouldn't shell out the cash if I didn't game.

This mouse is superb in pretty much every aspect that you can assess a mouse.  In overall usability, it's great.  It feels nice in the hand (albeit my hands aren't huge, but certainly not small) but it's still a size that makes it easily portable with a laptop.  One of my favorite features is the scroll wheel.  It's incredibly smooth.  Impressively, the scroll wheel has remained smooth even after years of using the mouse intensively (hours a day).  It's not as smooth as the day I got it, but it's still frictionless enough to scroll to the top and bottom of almost any page with just a quick swipe.  Another great aspect of this mouse is its ability to control aspects of the computer with the various buttons and directional scroll wheel.  Using it, I'm able to control my iTunes (next, previous, play, pause) and control the computer volume with the directional ability of the scroll wheel.  Battery life is excellent.

However, even with all of that said, the most impressive aspect of this mouse, for me at least, has been its durability.  I have used it for years now and I've dropped it many times on very hard floors.  Now, it should be noted that this doesn't mean I threw it down a flight of steps, but I'm talking about legitimate drops from an average height desk.  Sometimes after a fall the batteries and battery cover pop out, but never has the mouse sustained any damage whatsoever.  Maybe I've been lucky, but it seems incredibly durable.  I also frequently carry it around in my backpack and the scroll wheel gets pushed in pretty hard, but it's never broken.  Also, not to say the mouse is water-resistant, but I use this mouse so frequently that just in normal use, after washing my hands, I've touched it and gotten it wet numerous times.  Never any damage.

In the end, you really can't go wrong with this mouse.  I've bought additional ones as gifts and everyone whom I've given one to has loved it.
