In daily use, it has proven itself so far. I would buy again. Who - like me - will use but also in the bedroom at night and at the same time charge the phone, should not be too sensitive to light: The LED - which is on the product photos from - quite bright lights and in blue. One can in our bedroom in about 2.50 meters from the station make a 1 m wide (diameter) blue dot. My wife and I do not mind.
Therefore, I forgive only four stars: the LED can be switched off or Would not as strong, the product would be almost perfect. Last icing on the cake would be if the LED was red - that's at night to the eye most comfortable (eg light therefore, most alarm in red).
