I year ago I purchased 2 of these as a donation to keep Hot water hot and Coffee hot at a homeless shelter. They worked great everyday with out any problems. Originally I purchased the stainless steel versions of this product. These worked flawlessly for over a year of daily use. We found these were perfect for our situation over using air-pots. With Air-pots, they were expensive for the large ones and if accidentally knocked over the tops would inevitably break.Well the Aroma Hot pots have a larger bottom base and are much more weight to them then air pots and make them almost impossible to knock over.Why did i purchase two more as a donation? Well after a year of use, another volunteer decided to be helpful and on a Friday decided to clean them. I was not their so was not able to stop what they did. They filled them with water and bleach. Not just a little bleach but 1/4 gallon in each pot. Why? "I have no idea". These pots have a stainless steel interior that only require an occasional wiping out with a damp cloth. Needless to say when I came in on Monday the bleach had eaten through the gaskets of the pots. Which made them useless to use cause they would no longer hold water.I then decided to purchase and donate two more of theses to the shelter.But because of limited resources I purchased the white ones because they were cheaper then the stainless steel original ones.I have since put labels on them stating do not wash or clean on them.These pots are great because they have dual dispense functions. you can use the electronic pump, or the air-pump function. Note that the electronic pump will not work until the beverage inside reaches the temperature set. The air-pump dispense function is nice because some of our clients come in for a quick shower and change of clothes and grab a cup of hot beverage, before heading out for a job interview of their part time jobs.If were not for the helpful but damaging cleaning of the volunteer we would still be using the originals I purchased.
