The only drawback: you can only use the supplied AC adapter as it has no USB connector.
Possibly also fits another QI charger into the Fatboy pillow that I have not tried it since I currently have no need.
Pro: Fatboy shell feels good and sturdy and is equipped with decent marks for correct positioning of the smartphone.
There is no LED which might disturb the sleeper and no beep sounds (except the phone, if not switched off).
The current consumption of the QI charger when no SP is loaded, is about 0.3 watts in standby.
Cons: no USB connector on the charger.
