Have it installed by Lennar in a new house, worked well for 10 months (a bit noisy), suddenly stopped to vent, while lamp still works, but motor is not engaged. Repair service came in in 4 days waiting to be called in and repair..
So, now 2 weeks w/o the vent hood in a kitchen, who knows if it will be repaired or another visit is required. Will see. Because of reliability, can't give it more than 3 of 5.
