Summary: I had this mouse for just over a year when the lazer died out. For $15 it's worth it(i paid $35 over a year ago) but many seem to have issues with it dying sooner than a year. worked well, nothing special but i did like how it felt in my hand.
Summary: After 15 months, 2 weeks the mouse wheel just stopped responding correctly, and now skips a few rotations here and there. This mouse worked really well on a PC that is used 16 hours a day where mouse is used all the time, so I've had better luck then some here.
Pros: This is an updated review. I've used this mouse for just over 15 months. Feels good, tracks good, very nice for the price (was only $10 at time of purchase).
Cons: After a few months of ownership,,, once in a great while it would just randomly act as though someone had moved the mouse wheel one notch. I didn't have anything critical tied to the wheel so it really wasn't a problem for me.
Summary: I was hesitant when I was buying this mouse because I read the reviews and heard that the sensor goes bad quick. I guess I was kind of lucky to use it for a year and a few months.
Pros: The mouse was flawless when it actually worked. It was pretty comfortable. It fit perfectly in my big hands.
Cons: After a while the mouse sensor goes really bad. As others have said, it stopped working on mouse pads and doesn't react to movement at all. It would start stuttering and even stop moving. I had a nice time using it on a piece of paper for a while till it barely worked there.
Summary: and this is a big but: I have had this mouse for only a week. it has a nice design, if a little heavy for my taste, and it tracks wonderfully, but there is a major problem with it. It overheats.
Summary: I purchased this mouse for less than $20, It lasted more than 3 months, Then the pointer started to become jumpy. It is not like completely "stop working", it only works when it wants to. In the first 3 months, it worked perfect, literally one of the best gaming mouses for this price range.
