I can't comment on the rate of charging yet since I just got this in. My 1st impressions are good. It is super easy to set up, just plug it in and go. The charger does not care what angle you have you phone at. I have tested it in several different angles and it always charges. I also did not have a problem charging with a case on either. I test it with a Spigen Slim Armor and Ringke Fusion case and both case had no effect on charging. On the front of the charger there is a small light to let you know the phone is charging. The phone does not slide off the charger, the charging plate is made of a hard plastic. I don't think I will be going back to wired charging, I will need to pick up a few more of these.
