The Samsung charging puck is total garbage. It charges for like 10 minutes like a champ, then the blue light flashes and it stops charging. Some say it's because of the small receiver tolerance (needs to be placed with surgical precision) but why, then does the first 10 minutes work fine, then it stops. There is no earthquake. There is no movement. The phone was sitting there, not moving at all, then it suddenly stops. That makes no sense.
I have two TYLY VUs. They work 100% of the time 100% reliably.
Samsung is giving the pucks away to clear inventory. They know they have a stinker on their hands. Anyone who paid $49 for the Samsung puck should run, not walk and get their money back.
It's not the phone. It's the terrible Sammy charger. Get a TYLT and call it a day.
