I got this wireless mouse a few years ago before I went away for university and I must say it is one of the most useful products I own. Now many people might scoff at the fact that a wireless mouse isn't any different than a wired mouse but I beg to differ!
The greatest feature of the mouse is its ability to be used away from my computer. In my bedroom I use my computer to watch a lot of movies and I find the wireless mouse provides me with the opportunity to lie in bed and be able to adjust the volume and do various other functions. Also the mouse uses a duel laser engine which allows me to use it on various surfaces. The mouse works perfect even when it is applied directly to bed sheets, quilts, and any other surface! When using it on any surface anywhere in my room I find the mouse to be just as responsive as if Im sitting at my desk next to my computer.
The mouse itself is very easy to install, all you have to do is plug the USB attachment into your computer, wait for it to be recognized and you are good to go! From an ergonomic perspective it is very comfortable to use. I tend to sit at my computer for hours on end and my wrist never seems to get sore or tired. The mouse itself has a scroll wheel and it also has 2 buttons which allow me to go back and forth between web pages. These buttons are very convenient when I am doing a lot of web browsing.
Personally I think the only downside to this product is that it uses batteries (AA batteries). I find using batteries is somewhat of a hassle but the mouse has a little light that flashes red to indicate that the battery needs to be changed sometime soon. If the mouse itself came with a rechargeable battery and a docking station I think it would push this product over the top.
If you are looking for a wireless, laser mouse that is easy to use, easy to install, and comfortable handle then I recommend you try the Logitech Duel Laser Engine.
