I really like this unit, moves copious amounts of air and looks good doing it! Install was not easy, but managed to do with my just me, my 100lb wife and 12 yr old son. No, not easy, and required an extension for the drill, but we managed it just fine (and I am not a handy-man). Deducted 1 star as the lights are not very bright at all on high. Low is a good level, but not high. not sure I can replace them, but if I can, I'll add another star.
