Pros: Wow, I can't believe all the negative reviews. And are computers only used for gaming? I don't think so! I have owned several "name brand" (mostly Logitech & Microsoft) mice over 20+ years. This one by far it the best size, feel and precision. I do CAD work with it. It is very precise. It has the MOST handy screen snipping program (one drag-click from the top of the mouse) ~ I have ever used. I am buying another A4 now to replace my one month old LogiCRAP wireless $59...
Cons: The factory battery only lasted about two weeks. At least it uses a AA battery.
Cons: Mouse is very jumpy on me. It is never very responsive and will often turn off and I have to click to get it to turn back on. This makes this mouse worthless for gaming (which is what I intended on using it for) amd still quite awful for anything else. Yeah it's cheap but it's not worth it.
Pros: Price, good for desktop or laptop use, programmable buttons, tiny receiver that fits snugly into the bottom of the mouse, laser, the hole less design seems like it could be useful.
Cons: It feels somewhat cheaply made, noticed an occasional lag, just a little small for me. Not entirely sure about the company overall. Warranty period is a bit short and for a company of this type. This was the big hangup with purchasing this mouse
Pros: Love the 5 button setup with the mini button next to the scroll wheel. The mode switch button is also super usefull, I would otherwise not use the multimode option. CHEAP.
Cons: Studders after using it for a few hours. I've tried using it on diffrent surfaces but it still studders for a few minutes then magically it goes back to normal. Its annoyed me enough that I just ordered a logitec. CHEAP.
