We bought all Jenn-Air appliances for our kitchen remodel including this downdraft. We have used it a couple times and find it to be easy to use. It is by far better than our older downdraft and I can tell it is high quality.
We got this installed by our contractor in our new house we just built. It turns on and sounds like it is working but doesn't suck any air. It almost acts like it is blowing a little bit of air back in the house. Our contractor said there was no way to hook it up backwards or anything since it is just 120V power going to it and the repairman said it was installed improperly and that improper installation isn't covered by the warranty and the installer will have to figure out what is wrong. I would recommend this unit because it sounds like a strong vent fan and it looks nice and operates nice besides the fan not blowing any air properly but since it hasn't been working properly yet I can't recommend it... It has to be something with installation or maybe wireing was backwards from the factory...
