Excerpt: I am using computer from past 8 years or so and as a computer user everybody needs mouse, so do I. Actually I never bought a branded pc but I bought assembled pc. In past 8 years god knows how many mice I tried.
Summary: Optical mice are invaluable in a factory environment, regular mice with a ball are entirely too prone to gumming up. Frequent cleaning is necessary for regular mice, never for the optical. (Unless it gets so dirty on top that you don't want to touch it.) If you find your mouse cursor stopping, jerking, or going in a different direction than you intended with a regular mouse, get an optical.
Pros: Does not work well on transparent surfaces such as glass, clear plastic, etc.
Cons: Does not work well on transparent surfaces such as glass, clear plastic, etc.
Summary: I had been looking for a mouse to play PC games, nothing expensive or fancy, just something better than a mouse with a ball. The price is great too. This mouse has a great reaction time and lets me play games with ease. It also activates with the slightest touch. I'd recommend it to anyone.
