I bought one 10K unit to see how it went, loved it, bought a 2nd 10K unit, love it too! They are extremely easy to install, and these 10K units are more compact that typical 10K units and fit great in my smaller windows. The cover on the condenser fins prevents your fingers from getting sliced. They're definitely quieter than my old 10K units and don't interfere with TV or conversation, but they're not silent. Phone app works great! Automation settings work great! Very happy with these units.
