I had the Samsung fast wireless charger for my S7E and it made the phone very hot no matter what case I had on it. Ended up selling it.
I now have the Tylt charger stand and it works great with my Defender case, Symmetry case, Commuter case, and my SupCase. Doesn't heat the phone and does not charge at a snails pace. Only thing is that I have to use a spacer about the diameter of a pencil to raise the phone just a touch. Won't charge if it's sitting all the way down in the charger.
I'd rather lift the phone a little than have the phone burning up on the charger...
