I have only used it a few hours, though at the begining it had some problem disconnecting randomly after the next day it worked perfectly. I highly recommend it if you're new into digital art and don't want to spend a lot of money.
I was a little worried that this tablet might not get here safely, but the seller made sure everything was in order. Fairly easy to set up. The pen feel while drawing is somewhat stiffer than other tablets I've used, and will take a bit of practice to get used to. The screen is more blue than my main monitor. The pen is lightweight and comfortable, the overall size of the tablet is nice (big enough to draw on comfortably but doesn't take up too much room on my small desk). Overall a nice tablet to use at a great price point.
