Summary: Everything was perfect. The item is better than I expected. However sometimes seems like the receiver lost the connection with the mouse. I am worry about this issue. Maybe some radio frequency interference cause it. I am not sure, but I hope the receiver will works well.
Summary: My Usage: Graphic Designer, Gamer, Casual Net Browser Time owned: 1 year - every day use Pros: - Excellent, comfortable design - Feels of a good, solid quality - Battery longevity: not quite a year, but still very good. Expect 6 months from daily use. - Ease of use: plug in and go within seconds!
Summary: Brilliant. Bought to avoid RSI at work. Comfortable, adjustable and good on batteries. I like heavy mice, so I always go wireless. Combined with a steel series mouse mat, I can point so much more accurately without any overshoot. 2xAA batteries last around 6-8 months and I've had no issues so far.
