I know the Zojirushi is recommended a lot, but I'm not a fan. It certainly does a great job keeping stuff hot, but the silicon(?) parts pretty quickly takes on a strong smell of stale coffee that ruins it for me, at least when trying to drink from it directly. Pouring it out into a mug helps, but kind of defeats the purpose of it. I've tried everything to get rid of the smell but have not been successful.
