Pure gambling

I have this controller now sequentially ordered three times, because I had found similar problems with the device such as the 1-star reviews. The first controller worked beautifully and I think would deserve five stars because it fits comfortably in your hand, a place of loose batteries battery has and looks well made. The rubberised exterior also feels good.
Due to the positive experience with the first controller I ordered a second. However, this had the problem that he did not even went to without connecting the charger cable. No lights shone and the pairing with the FireTV did not work either. I sent this controller back as defective and ordered a new as a replacement.
But the new controller had virtually the same problems. Without connected power supply he was not, with power he had, after all, to pair with the FireTV when the connection went and lost again. Since I have not bought a wired controller, I will have to return this. It seems as if an entire production batch get a faulty battery or else it will be sold as defective returned Controller easy again. Looks like I had to look around for another controller. Again I go not risk. It's a pity because the first controller was really good.
