Query: only bad purchase from amazon

This is something my husband has asked for because of his outside job always made his coffee get cold to quick. It looked really nice and definitely kept his coffee hot, but then coffee would taste like the inner plastic liner after the first 5-10 minutes of being plugged in. Then after 2 weeks of use the charger port became loose and it would no longer work. It wasn't worth my time and money to ship back for a replacement....I just won't buy from that company again..
