Bests & Worsts Reviews from Amazon

I bought this as a gift for mom, fully aware of all the other comments. She never used a metal spoon and only washed and dried using a soft cloth from day one. Yet within a month, the interior coating began to flake where the side met the bottom. Customer service replaced it no problem, but we made the mistake of sending in the original box and did not get one in return - just a plain brown shipping box. She loves having hot tea from start to finish, but wishes the mug capacity was larger. I would get one for myself but not until it holds more! She doesn't have a smart phone but got the app on her iPad, so she customized the temperature to 142F. Four months from purchase, the spring on one of the charging pins failed, so it would no longer charge. Customer service replaced the base - we only had to send in a picture. I/we want to give this 5 stars (and we do give customer service 5 stars), but the continual problems are a concern and bit of bother.
