The range hood was installed a month ago. I didn't use it often, it functions well so far. My biggest complain is about LED lights. They are not bright enough. They don't focus on any of burners, instead they aim at the center section of the stove. You need additional lights to see better.
We remodeled our entire kitchen and looking for a suitable Ducted Under the Cabinet Range Hood. And my son recommended Cosmo 36 inches one. He also remodeled their kitchen and have installed Cosmo range hood. It’s amazing, works good on ventilating and quite too.
