I bought this product originally because I needed a replacement to the literally no-brand China-made OEM mouse which came with my computer, as it was going out (After three months of use I might add). The product took about six days to arrive (It arrived one day late as there was a delay which I didn't really mind) and upon arrival everything seemed fine and dandy, I unboxed the thing and used it a bit. At first this mouse was actually pretty outstanding, it wasn't the highest quality product out there but it did what at the time I wanted it to do - improve my apm and simply work. The problems started about three days later... Firstly, the mouse wheel began squeaking which I found extremely annoying. I opened the thing up to see why it was so damned squeaky, what I saw before me was clearly a design flaw. The mouse wheel rubs up against and into this piece of plastic which over a short period of time wears down and that plastic dust produces the extremely loud and annoying squeaking sound, because the wheel is literally held into place by this piece of plastic, you can make all the effort you want to clean it out or lube it up - It simply won't work, the squeaking is inescapable and will sometimes disappear but always ends up coming back. This wasn't the only problem however, a couple of days later I noticed that the left click button was simply not registering sometimes, which is exactly what I was trying to escape from in the first place (It is what happened to the crappy OEM mouse). I didn't bother sending this thing back, I lost the 30-day return policy and I think I may have thrown it away the first day by accident. Now and then I try the mouse out to see if maybe it'll magically start working normally again - and it does for a short while... Oddly. The left click button will work fine and the mouse wheel won't squeak for about an hour and then it will again. It is amazing that in all of the product reviews I have seen, NONE of these issues have even been hinted at. I now use a Dell mouse I picked up from my school for free... Reliable so far.
Overall 1/10 DO NOT BUY THIS PRODUCT.
