Product review (5 stars): WOW! Proline series 4 level superior suction!
4 count them, 4--button levels of air suction! Stainless Steel is not cheap but high grade & heavy thickness. My hood arrived in pristine condition & best packing I have EVER seen, so was well-pleased.

My 30" version of this unit has 3 removable Stainless Baffle sections which was FREE upgrade from aluminum screening, and the buttons are on the vertical front ledge of unit with a DIGITAL readout screen of the level of chosen suction and even has time-delay on shut-off = BONUS!

-Has a 3-prong plug to plug in and check if working the moment it arrived.
-The exit of the 6" round flu from motor has a butterfly damper that opens when fan engaged so will be great to prevent back flow from exterior.
-The two piece chimney surrounds are also heavy duty Stainless Steel and uppermost section has two sides consisting of a series of venting to dispel heat at top sides.
-The entire hood and two sections are protected by a clear or blue skin of plastic that is easily removed after installation.
-There is an included small approximately 2"X3" clear plastic topless box that has slots that slide into brackets under motor housing that is supposed to catch any accumulating grease from motor area low point that is accessed via the removable baffle. This then can be emptied and wiped clean with ease.
-Installation is easily done & straightforward...find the centerpoint of stovetop/range and have center of hood match this point and mark two hanger holes at level into studs with provided heavy gauge screws (rip open wall & install stud if not there--molly screws are NOT going to work here--after all won't be seen anyway as hood covers it).

Con:
-Two halogen lights are in rear of unit and are only 20 Watt each so total 40Watt so woefully dim for cooking surface...I have upper cabinets on both sides so I am installing under cabinet lights on both sides to compensate.

I have not permanently installed totally on wall yet as am doing some extension of wiring in wall behind hood in wall but will update when totally complete with photos. I am using the two baffles on interior two exits of blower motor but I am doing a hollow faux wood beam to cover the metal 6" flu system across the room to vent through out through bump-out dinette roof.

This hood totally blows away the competition at Lowe's or HomeDepot stores...and the price is at least $100-400 BELOW comps with these features anywhere online.
