Logitech Advanced Wireless Trackball

I have gone thru a lot of ball mouse's. Usually it's the primary button that goes out or one of those little plastic bearings gets a flat spots on them that causes the mouse to loss pointing features. Using them for gaming while sitting in a chair is one of its best features. But I have found that regular old side mounted ball mouse work just as long as a 100.00 mouse. All those switches to increase performance and speed do help some but when in the middle of a game and you accidentally push the switch that causes the enhancement is a bummer. So you have this expensive mouse that has sw/ on the bottom side the side that you end up never using. So this Logic mouse is reasonable priced with fast response and pinpoint accuracy seems to be working. Being pinpoint accurate helps in getting in between words to edit pushing those little arrows on the side to center screen roll etc.. I haven't had this mouse long enough to know whether it can get past the 6 month use mark that's most start to fail. Nor know how long a cheap (off brand) or expensive (Duracell) battery lasts. I've have rechargeable mouses that have outlasted most mouses before going bad. I wish this mouse had away to use rechargeable batteries. Now the top buttons next to the mouse ball actually seem to do something helpful. The ease of use is good. Buttons so far so good but I have just gotten it. If I can get away to update this in a couple month I'll update its performance.
