Not for "middle mouse click" users 
2008-03-27
I purchased two of these, and they perform well except for one quirk. The click wheel in the middle is stiff and unresponsive. If you rely on using the middle mouse button to select items on a webpage, avoid this model. I often have to click several times to get it to work; in the process, the wheel moves and I am no longer on the area I am trying to select. I will be replacing this product with another soon!!!

the pointer moving what I expectation very good, Fit with my hand not too big not too small. Easy to used it.
Better than Intellimouse Wireless Explorer 2008-03-26
I replaced my MS intellimouse wireless explorer with this and this one is much better. That one was big and clunky and I never used those side buttons. This one has the tilt scrolling wheel for left and right scrolling which I find very useful. This also has a smaller footprint and easier to hold. It is symmetrical, so easier for left or right handed operation. Amazon's gold box deal made this almost as sweet.
A nice mouse for desktop only 
2008-03-26
The mouse is doing a good job that I am satisified. However, I didn't expect the same size USB receiver now connecting to my laptop with a 2 foot long cable!
Nice, but why bother? 2008-03-26
The mouse may be wireless, but you still have to plug in a base, which is fine if you have a pc, but is not mobile enough for a laptop. If you are sitting in a chair and the base for the mouse (base is attached to computer by cord of course) is sitting out of your way on a side table, then mouse won't work. For the base to be close enough for the mouse to work, then the base and its cord are in the way, defeating the purpose of wanting a wireless mouse. I prefer a true wiress mouse, with no cords leaving the side of my computer.
God performance, but some OS issues 2008-07-07
I really like this mouse design. Its symmetry makes it appropriate for both right- and left-hand mousers (I'm ambi-moustrous) and it has smooth, quiet controls.
Unfortunately, one of the "special functions" available with the programmable tilt wheel is to show larger views of the running applications (screenshots of each running ap, instead of the icons you see when you do an Alt-Tab). To accomplish this, it actually has to take mini "Print-Screen" pictures digitally whenever your applications show a display, and this causes a rippling or repaint effect in some applications. At least in may versions of Windows XP this is the case.
Even if you don't USE that function of the tilt-wheel, the software still takes the screen shots. So the only way to eliminate the rippling screen problem is to uninstall the software that came with the mouse and install an earlier version of the mouse software - which does not have the tilt-wheel (scroll side-to-side) functionality.
Nevertheless, it's a smooth operating mouse, attractive, and seems to have a reasonable battery life.
Nice mouse, horrid wireless 2008-04-03
Mouse has a nice feel but is not consistently smooth in operation. Missed button clicks, sluggish mouse movement, and other wireless oddities ruined the experience for me. I returned for a full refund.
Mouse 
2008-03-30
I have really not used this since I evidently didn't read the description really well & it is for a desktop. My order did come in very quickly
Wireless Optical Mouse 2008-03-30
This is a great mouse (although a tad big for a woman's hand), but worth the price to get away that pesky cord.
Be aware, though, that when you share an office with someone that also uses a Microsoft Cordless Mouse - you can get interference with each other when you are using them at the same time.
Felt like a left-handed mouse 2008-03-28
I'm a right-handed person, but somehow the fit was not very comfortable in my right hand, even though it is a large mouse, and i am comfortable using a variety of mice. Moreover I was looking for something without the extra receiver it comes with. went with a bluetooth mouse, since my laptop is bluetooth enabled. I'm happy ever since.
