Extra Charging Coaster 2: Ember Mug 2

This extra coaster works great. I'm only giving it 3 stars, however, because it's the 3rd replacement coaster I've needed to buy-- two previous ones failed to consistently and reliably deliver a charge. I think it may have been something with the two charging pins not staying firm enough to contact the rings on the bottom of the cup, but it was completely annoying to spend 5 mins each day trying to line the cup up so that it would accept a charge.

Good Product. . . Except

The product works very well but I feel the charging prongs is the weak link. My son and I have had a total of four Ember cups. We've been through double that with regards to chargers due to the prongs breaking (specifically they stop springing back up). We make sure the bottom tray stays dry other than a little water after washing the cup. I've read other reviews where they too experience the same symptom. Otherwise, it's a solid charger just hope they improve the spring design.

Enjoying hot coffee again since receiving my charging plate. It was the solution to the issue with my cup not charging.
