I never have cold coffee or tea anymore while working!

My favorite tea cup has a concave bottom so none of the warmers worked

But they will definitely work for this Voolta mug warmer because they provide this aluminum thing that goes in between the mug's base and the warmer itself, and it helps a LOT to keep the coffee/tea hotter and for longer

It keeps my tea hot and looks nice, too

I like my tea very hot and was worried that the unit would just keep it lukewarm like other cheaper versions.

However, I have placed warm tea/coffee on the warmer and it does make them hotter

At least you won't have to tolerate ice cold coffee or tea at your desk

It is very easy to clean and it keep my tea my nice and at perfect drinking temperature

Been using it all last week and haven't had any cold tea in the
