I wish I had looked more closely at the reviews, there are only 6 reviews. Buy something proven. The stylus works very simply, right out of the box. You push a button, it's on. Bluetooth pairing is not required. However, the application I use does not recognize every movement of this pen. There is also no palm rejection, which I can understand. All in all, save $ and good luck finding something better, at least for the Galaxy Tab A. I'm looking again.
