Product review (5 stars): Great unit, at least the first 2 weeks!
wife loves it. replaced an 8-yr old Jenn Air smooth top with downdraft built in. Cooking is so much faster. Have a grey countertop. this fit right in.
Love the fact the glass does not heat up, just the pans. Am leary of all touch rather than knob controls so will pay for long tern warranties.
I managed to wedge a Whirlpool downdraft behind this unit to barely fit a 24" counter. As to how deep the unit is, go for the Mfgr website not the installation instructions or retailer's websites that exaggerate the depth front to back.
