The mouse works great, and does exactly what it's advertised to do. Unfortunately, after this one wears out I shall be returning to a Razer Naga mouse.

First of all, within only two weeks of having it, the fabric that sheathes the entire cord began to fray. After a section of it wore through, the cord inside began to bulge outward and now has a permanent loop to it, which often gets snagged inconveniently.

I was saddened to find out that the button for switching profiles cannot be reprogrammed. As I primarily use my gaming mouse for League of Legends, a terrible game that I do not recommend anyone else playing, I usually program the two buttons a bit further back from the mouse wheel for the summoner spells. Conveniently, many gaming mice have two buttons there, and there are two summoner spells you can use per League match. The Naga let me program both of these, but this mouse only allows one of them to change.

My biggest complaint, even more inconvenient than the cable loop, is the width of the mouse. I knew when I ordered it that the mouse was wide, but I did not expect to begin experiencing pain and discomfort in my pinkie finger if I use the mouse for even short periods a day. As I work in IT by day and often game by night, I am unable to use this mouse as much as I need to.

Works exactly as described. Nothing too fancy about it. Only reason I knocked off a star is because the USB receiver doesn't store flush into the mouse, it sticks just enough to annoy me. I suppose this is designed to make it easier to get out, but it means the mouse won't sit flat. Other than that, works perfectly.

This product does exactly what it says it will do.  As for other reviews, try reading the manual, it was easy to pair via bluetooth AND if you push the CAL/KP button, numbers are then input directly on your computer.  You do not need to hit send every time.

Realize that for serious data entry though, it will NOT replace a real keypad.  For full time use, it will NOT replace a good ergonomic mouse.  For someone like me who uses a trackpad 95% of the time, but likes having a mouse around for a small amount of design work and data entry, it is perfect.  Some drawbacks, the keys are smallish and unless you are very gentle the whole mouse slides away from you 1/8" every time you hit a key.  But it is still quicker and more intuitive than using the keys along to the top of the keyboard.

The product is exactly as advertised, and works great. I'm very happy with this purchase

I can't consider myself much a fan of gaudy, LED-lit "gaming" devices, but seeing as my mice have a nasty habit of scroll wheel failure, and I wanted a mouse with a relatively high DPI at a relatively low cost, the M601 fit perfectly.

The fit and finish are higher than one would expect; I believe I only paid about $14 for the mouse, and it feels very solid, much more so than a $15 store-branded or iHome mouse. In addition, if one finds the mouse slightly too heavy out of the box, the adjustable weights in the stock allow for some leeway. The Teflon coating provides an excellent sticking surface for the hand in addition to keeping off excess dirt and grease from continual usage, and the bottom pads slide effortlessly across any surface. The only minor nitpick I have is that the shape is a bit unnatural for my somewhat small hands, and my ring finger rests somewhat uncomfortably on the edge of the right mouse button. Otherwise, it functions flawlessly, and there is probably no better/more versatile mouse for the price.

My 1-year-old laptop lacked built-in Bluetooth (d'oh!) but this mouse works fine with a Zoom Bluetooth PC Card. I leave the card in the otherwise useless slot, and voila--no more fiddling with my dongle. HOWEVER--the CD supplied with the mouse contains Logitech's SetPoint software, which apparently only works with a keyboard/mouse combination. The program wouldn't even start up. I uninstalled it, and the mouse worked fine without it. All I needed to set up the connection was the utility for the Bluetooth card. I find that this mouse gives much smoother scrolling than the Microsoft wireless mouse I was using, which costs about the same and uses an annoying USB transceiver dongle that you have to remove and store under the mouse to turn the batteries off--after just a year, the mash-switch got wonky. But the V470 has a real, on-off switch and a push-button "connect" switch. No problem, no fumbling.

Mouse is as advertised. I bought it for an iMac that needed a new mouse. It is compatible with PC and MAC, which is awesome. Simply plug in and go! Would order this product again!

The purchasing experience was brilliant, shipping was fast, and product came with all the intended pieces (mouse itself and dongle). The mouse has an optical sensor which does not emit any visible light when in use, however the mouse works on many different table surfaces including wood, glass, sofa, chair, lab table finishes, and school desks. The actual mouse buttons and dpi settings work as advertised and the mouse wheel has a nice feedback to it. The mouse is light enough to be appropriate for portable use in your laptop set up.

Works as advertised. 1 week in, and no problems to report. Last mouse I had was dying, as it wasn't meant to game, but was just a cheap temporary replacement. This one handles beautifully, and I'm looking forward to many hours of precision.

This mouse has been great to me. The main reasons I bought it were to get rid of annoying wires, and to open up more USB ports. It did both of these superbly, seeing as it is a bluetooth mouse.

The size is relatively big, even though it is called a "notebook mouse". It is also symmetric which allows for left handers to easily out the mouse to use.

The battery life is good. I use rechargeable batteries so it won't cost me anything to replace the batteries.

The connectivity is also good. I RARELY have problems with it not being recognized by the computer or something like that. It goes to sleep after like ten minutes, so you have to shake it, causing a slight delay. But that is power being saved when it is sleeping, so again no complaints. Setup is also very simply as long as you know how to use bluetooth devices and read the directions.

I am very happy with this product.

It does exactly what it promises, and works wonderfully.

The mouse does exactly what it needs to do, it works as a comfortable mouse. The plastic top is a bit flimsy and actually popped off during normal use and had to be put back on. Don't let that deter you though, the ergonomic feel was very comparable to higher end mice that I have used. The battery compartment is on the bottom of the mouse which takes 2 AAA batteries. The batteries are offset a little bit on top of each other. This makes the top battery real easy to get too, but the bottom battery.... Let's just say you need an engineering degree, safety glasses, and a small screwdriver to pry the little battery out of place. I may have broken what little nail I had trying to get the battery out without any tools. A battery pull tab would have been really helpful if it was added to this mouse. I was testing this mouse on a slower dual core 2.0 Ghz machine, and I had some lag occasionally. Even with a mouse pad I was experiencing some hiccups. I wouldn't recommend the mouse for gaming, otherwise you might miss that perfect shot trying to look around. However, when you are in a pinch and need a comfortable mouse for regular computing, bring a screwdriver and enjoy this inexpensive portable mouse.

It's a great mouse, that's for sure. Here is the full review:
-Buttons may feel stiff at first, but with enough use, it loosens up a certain degree that I really like.
-Great build quality, mouse hasn't broken on me, LEDs still functional
-The logo is smaller than is presented in the pictures
-Sensor is extremely good, doesn't spin out, can detect flicks
-Side buttons have good feedback and I like to press on them
-Slight rubber coat feels great, although does take quite a few fingerprint after awhile
-Mouse feet are big, thus making the experience even better.

Now for the few reasons why this isn't a five star
-As a mac user, the USB doesn't have the best time working with the mouse, it often disconnects now, and has gotten to the point where it tremendously affects my gameplay, and this is the biggest issue that I've had. When this happens, the LEDs are sometimes on, and sometimes off, but the LMB and RMB don't work and the sensor doesn't track. I don't know if the issue is with the mac, but it wasn't like this when I first got the mouse. This is a very big issue that affects me.
-The cable is very stiff and hard to untangle, and it is an ugly red color.
-Mouse tends to get wet with 1+ hours of use with sweat
-Scroll wheel doesn't seem to be quite responsive enough, and is not really high up on the mouse, so the middle click is hard to use.

But other than that, it is an amazing choice for a mouse, and is my number one of all the mice I have owned so far:
Razer Naga
Razer Deathadder
Razer Naga Chroma
Logitech G502

And I also believe it is the more superior choice over the SteelSeries Sensei Raw.

*If possible, Amazon please send a new copy as this may be a defect, or contact me about it.

Hope this helped!

This mouse works exactly like it's supposed to. Solid clicking and wheel movement. It all feels very quality. My only complaint (and it is super minor) is that it doesn't quite feel right in my hand, specifically where my right thumb grips on the left side of the mouse. I use my laptop on the couch, so I'm always using the mouse at less than ideal angles (as opposed to at a desk), so that may have more to do with it than anything else. I highly recommend this mouse.

This is a great mouse.  I didn't have any trouble setting it up.  It works great!  Fits nicely in my hand and there isn't any delay in it at all.  Works flawlessly.  I don't have anything bad to say about it.  Good purchase!

This mouse is GREAT! The wireless USB thing can be stored in the bottom of the mouse. The mouse is a perfect size, not too big, and definitely not too small. It grips my hand very well. My only complaints are that it is difficult the get the wireless USB think out of a USB port and the wheel has no texture to it, so you don't know if you're scrolling or not. There is also a button on the left side of the mouse that is set as a back button for browsers, though you can change it to do anything.

This mouse does everything I expect & wanted, it's light, comfortable & accurate - the battery life also appears to be good.

However it does have a flaw for some people & in typical Microsoft fashion, they are either ignoring the problem or denying it exists. Whenever I use this mouse my screensaver stops working, swap to another mouse (& remove the drivers) and it's back working - swap back & it stops..... etc, etc... It can't be anything other than the mouse itself or the drivers, but over & over Microsoft offer no help.

I like the mouse enough to keep using it & shut my screen down when I'm done, but for anyone who needs/wants the screensaver, be warned.
