this is an excellent unit - very pleased. its getting a bad rap on many reviews, the fan does run all of the time - but its a circulation fan, its supposed to run all of the time. Some folks feel that this is due to an inadequate cooling unit that "cant catch up" Would be helpful if Newair provide more detailed instructions on how to maintain humidity in the unit. Other than that, if you've never experience cigars kept in a temperature and humidity controlled environment, you don't know what you're missing. The flavor opens up dramatically...
