Works like a charm. Just make sure not to place any steel/magnetic substances behind your phone.
My phone cover has a small steel piece to make it easier for phone holder. But during wireless, the charger gets too hot. Later on I found out that I had to remove the steel piece in order to get proper charging.
If you also use magnetic case, then you have to use this wireless charger with your your phone cover. If you use normal phone covers, then make sure that the cover is not thicker than 6...
