I use it every day. Takes about 3 - 4 hours to make a batch of water. You should see what is left over on the bottom, you will never drink tap water again! This is my second one, the first lasted almost 2 years. It would have been longer the the plug wore out. So be gentle plugging and unplugging the power cord to the boiler and the cord to the condenser. Overall, definitely worth the money for the cleanest water you can drink
