I have purchased the device because it is praised as the best charger repeatedly on the Internet. The charging function is also fine. Shortly after the purchase of the equipment sat with me from the display so that could only be guessed if the battery is charging or if it is already full. Amazon has replaced the unit. Today in this device, the display has failed again. The right of return is now over but, so that I stay now sit on a machine that is faulty.
