Looking for "mouse like movement"? Keep looking...
580345
I have read other reviews and seen the video of a coustomer saying there is nothing wrong with this mouse and my final review it that this is a D item on a report card. Slugish movement that does not offer much of a advantage over a regular controler in a first person shooter. I play Team Fortress 2 and while it helps a lot, it is impossible to have the movement of a PC mouse. I have tried tweeking the sensitivity every wich combination between the game setting and mouse setting and there is no great setting to help the movement. overall it helps but not to the level to allow one to play to there full potential...

Despite the mixed reviews, this mouse was too close to what I was looking for to not give it a try. (Good price, too.)

--== PROS ==--

Price

Wireless

Tiny USB dongle, but not too tiny

Very lightweight, yet still heavy enough for perfectly precise movements. (not sure if all people like lightweight, but I do)

Nice design & comfort (for those who like small mice)

Has DPI button (sensitivity adjustment)

Tiny lift distance (lifting the mouse off the mousepad, to reset its position, doesn't move the cursor much, like some mice that keep moving when the mouse is well off the pad)

Batteries have lasted a few months, so far, with daily use.

--== CONS ==--

At times, the wireless connection starts dropping every couple seconds. (each little blackout lasts about 1 second.)

During the first month of use, holding down Left-Click often did one of the following:
1) double-clicks
2) doesn't click at all
3) lets go of your click prematurely
4) continuously clicks over and over
After a month, all of the above issues went away.

Middle-mouse click sometimes doesn't work, and is very difficult to press down.

Turning the mouse off resets the sensitivity back to the highest.

I have used this mouse for 3 months with my laptop.  Look/feel and general use are fine for short periods of time (~< 1 hour).  However, I am currently shopping for a replacement as this mouse has one problem:  Intermittently, after clicking/double-clicking, the mouse will go into a "move to the left" mode...and will continue to move until it reaches the edge of the screen.  Sometimes it will move to the upper-left.  This is so inconsistent as to be unpredictable.  I will often (at least 10 times in a 30 minute period) have to give the mouse a wiggle to stop it from continuing.  Frustrating if you are trying to click through a multi-level menu, for instance.  Another example is if you working on any CAD-type or image editing project where you need to insert a line one segement at a time (mouse will move when it feels like it).

It was ok for a while, but now it is annoying...going to buy a replacement.

If I have to buy a replacement for a product because of how the product performs at an early stage in its life, it gets no more than 2 stars.  It could be just this one particular mouse, but then that points to lack of QA at the manufacturer end...again, 2 stars.

The mouse is great in a number of ways - size, color,  on-mouse USB storage, and the battery saving on/off. The only problem is that it's pointer/cursor movements aren't smooth, but rather I have found them to be quite wiggly. Had I known this, I would have gone with the comparable Microsoft mouse.

I bought this mouse mainly for the four thumb buttons. I figured it may work for mapping them to WASD for movement. The problem is, you can't map most keys on the mouse to a keystroke, so I actually had to create a macro to do a single key press for each one. It took a while to get it all working just right. I also had trouble with macros working in different games (SWTOR, GW2 beta, and Rift). Finally I gave up, and went with a Logitech G700, which so far, I'm very happy with.

This mouse is made to mesh with World of Warcraft, even with the ability to assign key maps to the various buttons from inside the game. While I'm sure it does great at that (I don't play WoW anymore, so no first hand experience), it's just not very good for any other games.

Bottom line, if you are buying this mouse for World of Warcraft, you'll probably be happy. If you're buying it for other games, look for something else.

Retired this touch mouse after using 1 month. I Disabled all the touch gestures, even then it moves my screens. Went back
to my old mouse and it works like charm.

This is an interesting mouse, it tries to run on its own! Seriously, never seen a mouse move pages and go to corners on its own. This mouse has serious issues. However, it is not a show stopper - i disabled almost all the gestures except for scrolling.

I really want to give this mouse 5 stars because it is silent and very comfortable to hold. However, this mouse does not do the basics of what a mouse should do. The cursor moves around the area of what you're trying to click. It gets super annoying because mouses shouldn't do that. If I move my mouse a little bit to the left, the cursor should move to the left a little bit. Instead, the cursor jumps around in that tiny radius. Also if I lift up the mouse a little bit, it still is tracking it and my cursor jumps crazily across the screen. But yeah, with wider movements, the cursor is okay. But if I want to move my cursor a little bit to hit a specific area, it jumps around. Disappointed because I love how comfortable the mouse fits in my hand.

This mouse isn't what I expected. Since I spent a lot of time trying to pick a mouse that was both "wireless" and had a good number of "programmable buttons" for gaming on my laptop, I was somewhat disappointed. The button setup (see below) was EXTREMELY disappointing for me.

Pros:
It is wireless. It does have two extra buttons on the side (I can use 5 buttons, in total (see below)). It is comfortable. It seems responsive enough. I like the "grips" on the side.

Cons:
Advertised as having "7-Programmable Buttons" but it only has 5 actual buttons. The other two programmable functions are Mouse Wheel UP and Mouse Wheel DOWN. These are not button presses - they are scroll functions. Personally, in my gaming experiences, it's easy to accidentally SCROLL when you're trying to CLICK the Middle Mouse Button in the heat of combat! I tend to NOT program the scroll up and scroll down functions for that specific reason. Had I known these two functions were counted as "buttons", I never would have bought this mouse. SO I bought a 7-button mouse with only 5 actual buttons. I was expecting the two middle buttons (shown in images) to be programmable, but I have no idea what they are for. One press seems to center the cursor on my screen...I'm not sure what the other button does. Nothing that I can see. NEITHER of the two middle buttons on the mouse can be programmed - they don't appear in the programming software AT ALL.. Basically, I now have a 5-button mouse with 2 useless buttons that I can't program in the first place.

It's ok, and perhaps this is just a facet of the form factor, but clicking things -- especially trying to middle click -- drove me nuts. You either had to death grip the thing with your thumb or the cursor would slightly move when clicking. This lead to a LOT of mis clicks or clicks that register as click-drag events. Ultimately I really didn't like it.

I ordered this mouse along with my new laptop three weeks ago, and now I'm already shopping for a new mouse.

First of all, after couple minutes of not using, I have to somehow shake the mouse in order to get the pointer move again. Especially when my laptop goes into screensaver mode - a simple "twitch" doesn't do it. I have to shake my poor mouse like a madman to get out of the screensaver. Second- scrolling is very choppy. Sometimes I scroll down, and the scrollbar moves up (and vice versa). Also, sometimes I have to click twice because nothing happens on my first click.

I'm so disappointed that I spent this much money on this mouse. Kensington needs to work on some quality testing before releasing their products.

Like right now, after typing this review, my mouse isn't responding again so I just had to shake it couple times to click the submit button - that is, if I can get it on my first click...

I really do *not* recommend this mouse.

In general I really enjoyed the mouse.  It has a nice look, and ergonomically it has a very nice feel.  However, it is way too sensative as to where you put pressure on it in order to get a click response.  I found myself clicking 2-3 times in order to get the click response.

I distinctly hate wheeled mice.  I always find dirt and detritus in the wheel after use.  This is why I liked the earlier Microsoft mouse that had a metallic contact stripe down the center.  It was a clinch to keep clean.

However the touch sensitive pad on the top of this thing often errs IF you're like me and rest your fingers on the mouse.  It can't differentiate between a left click and a right click if both your index and middle fingers are on it.  You have to lift one of them up otherwise you might get the alternate choice.

This took me a few days to figure out and it is very awkward for me to make that adjustment.  It goes against the natural movement of my wrist, which is to relax.

So if you can fit yourself to the tool instead of having it to fit to you, this is the mouse for you.

As stated in many of the reviews, you'll love it or hate it. I appreciated the sleek design and minimalist approach. Just because it doesn't look or feel like others mice I'm used to does not mean it is inherently bad. I had no problems having an intuitive interaction with the product. I actually liked the way it felt in my hand, scrolling was very smooth and the next/back swipe control is great. But unfortunately this product has one critical fault I can't overlook.

The major pitfall for this device is the absence of middle click (aka. mouse 3, mouse wheel click). I really wish I had studied more before purchasing, as it is mentioned in several reviews. Hopefully one more will help the next guy.

I do lots of CAD work in a Linux environment and mouse 3 is a common control used for panning or tilting. Without it, well, I cant work without it.

Some people will reply to this jabbering about SetPoint software (provided by logitech) allowing additional features, but this is nonsense.
- Middle click has been a standard feature in mice for a decade or more and shouldn't require additional resources from my computer.
- SetPoint is windows only. No Linux/Mac support. So no luck for me.

Back it goes. Dang, I liked this one.

I am so disappointed.  I love the feel and size of this mouse (I've had one just like it before), but I am going to have to throw it away.  It's movements lag and are not accurate and I have very little control over where the pointer goes (rarely where I want it to).  So frustrating.  Wasted my money.

So this mouse is super cool, but after a few months it started doing the same thing that the normal non-multi color chroma does where it double clicks and every day is almost a living hell when it happens. Like right now. It's just enough to tilt me in any and every game, even if I was totally fine before. Please tell me you fixed this is the new crazy lightshow one, because your mice are so comfortable and feel really natural, but this has happened to both mice (Razer DeathAdders) that I have and I just. Ugh. Dealbreaker for my next mouse.

This product (Keyboard and mouse) works great if you don't play a lot of games and have to use both the keyboard and mouse at the same time, but for me, whenever I'm using like the W key to move forward and I want to use my mouse to look around me, I stop moving forward, or I end up spinning around, haha. And it seems to only happen when I try to use them both at the same time. I'm not sure if it's a connectivity issue with the two items or what. I might go back and try the wireless mouse and my wired keyboard and see if that fixes the problem.

It's a real shame though that they don't work together, because I really love the way they look and work. (Minus when you gotta use them both when playing a game.)

The mouse feels good, but it tracks so horribly that it's basically useless. Steer clear.
