After shopping and reviewing products for many weeks I settled on the ZLINE Outdoor Range Hood. It appeared to have the best quality materials and components at an affordable price. I purchased the ZLINE to exhaust smoke from my built-in 32in Paradise Grill. When our home was built I had the builder stub out with a through the roof 8in duct. DIY installation took a couple of days but I was very pleased with the results. The ZLINE provided ducting, after a little modification to shorten it, connected perfectly with the existing ducting. I've used the Range Hood venting several times and it seems to pull the smoke off adequately. The vent fans are a little noisy at the highest speed but it's better than having the cooking area full of smoke. The four star rating is because of the noise. I would recommend this vent hood.
Purchased the hood with the remote blower with dual motors. Well worth the investment since we purchased a Wolf range top that required more 1200 cfm hood. Vented out through the roof with blower in cubby hole above kitchen. Looks great and keeps the cooking odors out of the rest of the house. Pretty easy to install if you plan it out before hand.
We purchased the dual motor remote option to minimize noise at the hood yet still attain maximum CFM. I'm an audiologist and can carry on a conversation with anyone in the room, even at the 1200 CFM setting, and hear perfectly. The removable grills are easily cleaned in the dishwasher. The remote motor installation was a little tricky but my husband is an engineer and handled it well. Having the remote motor made hanging the wall hood very light and easy to install. Overall, we are very pleased with the product living up to the specs.
