Extra Charging Coaster 2: Ember Mug 2

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.

The charging coaster works fine so far but the older one it replaced stopped charging from an issue with one of the contact pins not making contact with the mug. This is the 2nd time I had to replace the coaster. The coaster should last more than a year!

It's too bad that Ember hasn't changed the design of the charger over the years to avoid the condensation that occurs when charging which then corrodes the charging pins for the mug.
