In operation a little more than two years, the last month I do not use it at all. It all started with losing connection with the phone for some moments, disconnecting and reconnecting. Now everything is up to the contrary, it connects and immediately loses connection. Rebooting the phone doesn't help. Someone from the users drew attention to a possible problem in the swivel joints, I also came to the same conclusion. Although the position sensor is probably buggy. To pay tribute to the manufacturers, the quality of materials and assembly is on top.
