I can't review something I haven't received yet.

No comment for now Christmas gift for my granddaughter

When I saw this product on sale, I was surprised at the low cost/value. I had seen other wireless chargers and mug warmers but not together at this price. That being said, I am disappointed that the wireless charger doesn't work when the phone is in its case. To use the wireless function on this unit, you must remove the phone from its case every time you want to charge it. Also, the wireless charger and the mug warmer don't work at the same time, you must choose which to use each time you use one. Finally, the function switch is very cheap and could easily break.

charger is slow and it don't get as hot for the coffee warmer that i would like. its ok.. just slow

While the device does charge a phone albeit slowly, or keep a beverage warm, it cannot perform both functions at the same time.
