This seemed like the ideal coffee maker for work, since it is a French press and thermal carafe, all at once. So far, I am not so sure. It does not keep the coffee as hot as a traditional thermos, but I think that is inherent in the cylindrical shape needed to make the French press work. Also, a lot of grounds are making it past the screen. I am going to try a courser grind - that may help. I have been using auto-drip grind.
