Overall it's a good unit for my small bath & dressing room in an old house. I can't give it 5 stars because of three reasons. 1) I had to return the first unit because the "increase" button on the front panel didn't work, 2) In order to get the proper "tilt", I had to dispense with the installation as shown in the book and come up with an alternate method. Works, but not as shown in the book. 3) The unit has shut off completely on its own, it's happened twice, usually after just a few minutes after turning it on. Not sure if there is some sort of auto shutoff due to some condition I'm not aware of. I've made sure the delay feature is cancelled. But otherwise, I'm pleased with the unit and it's making an uncomfortably hot and humid space much "friendlier".
