Summary: I bought this mouse to replace my beloved Microsoft optical mouse as the left click button had worn out. I wasn't in love with the Verbatim mouse when it first arrived, and after using it for a few months, I've reverted back to the Microsoft mouse and just deal with having to click 2 or 3 times. Pros: Love the blue color. The overall ergonomic design of it is comfortable, and it works as one would expect a mouse . . . most of the time. See below for details.
Summary: This mouse looks really nice, has the forward and back buttons, and that is list of the good. The bad is that it is even cheaper built than the price would indicate. It is very light, not terribly comfortable, and not at all precise. I got this for a bit of comfort while using CAD and I am not shopping for a different mouse. It actually jitters a lot when you are moving making it a pain when I am trying to click on small features.
Summary: Pros: Great size (medium). Great shape. When working is smooth. Includes batteries. Cons: Highly sporadic as far as working is concerned. Sometimes laser shuts off and will not come back on without much trial and error of removing batteries/receiver. Sometimes laser is on but will not track. Overall: Two stars because it doesn't work very often. Feels like a waste of money even though it was fairly priced. Would not recommend.
Summary: Until today, about a year after purchasing, the mouse that came with the package works as designed, but the keyboard doesn't. After rebooting, replacing the batteries- it died. Why I purchased it: Wireless Small Footprint The good: The keyboard had a decent touch. 99% of the time, I didn't have connectivity issues. The disappointment: Premature death Lack of quality materials for a high use tool. The mouse that came with it works great is still functional.
