Bests & Worsts Reviews from Amazon

I have been using Microsoft's basic optical USB wired mouse for years. Everytime I try something different I end up going back to MS mouse. The thumbwheel usually goes first in my experience. I have had this mouse for a month now. This mouse feels and performs exactly the same as the MS basic optical mouse. Pointer movement is accurate and scroll wheel feel/operation is very good. Button clicks are good. Not too hard or too soft. I have med-lg hands and never had a problem with this size mouse. Installation was plug and play with Windows 7. No drivers to install. Wireless operation has been flawless. The top of the mouse is rubberized synthetic that does absorb oil from your hand and fingers.. Easy to clean with windex though. I got the mouse on sale. I really like it. I will keep using it until stops working.. Oh. almost forgot it tracks well on my sofa as well. Considering sale price -$15 and smooth operation. 5 stars Batteries are easy to install. The +/- terminals are molded into body. Don't understand the complaints about difficult installation. Update 7/5/12 5th month: Still working perfectly. Batteries last one month if you don't turn it off. Update 1/25/2013 1 year still working fine Update 8/8/14 2.5 years and still working. I use it everyday.
