Review on Logitech M171 Black and Blue RF Wireless + USB Optical Mouse with 1000DPI, Ambidextrous Design by Kiril Nikolov ᠌

Basically all computer "life" I use this firm. I like. There was one from Genius, one from Microsoft and one from Lehmark. I liked Logitech the most. They didn't let me down. They served for several years each. Has pros: Good, reliable mouse. Been using blue for over 3 years. Now I've got the red one. Some cons: Replacement due to contamination of the wheel. Scrolling through pages/documents with the wheel has become torture.
