I'm a die-hard coffee drinker and have used pump pots for years. This was purchased last year and here are my thoughts:
1) Will keep coffee hot and fresh for hours. Not luke warm, but almost as hot as when first brewed. (This at the end of 8-9 hours)
2) Large push button often sticks and it's difficult to get it to release.
3) Hinged-lid is not very stable, mine broke within months. Pot still works, I use mine daily.
4) If you can find the one they make that has a lever-type pump, in my opinion, it's the greatest way to go. Not only does it pump better, but lastt longer also. Only replaced mine because I broke the liner and couldn't find a replacement at the time.
5) These are awesome for retaining heat, look nice sitting on the counter and you'll never again have to drink burnt coffee.
