I purchased this about couple of weeks ago to replace Under the cabinet microwave (with vent). The installation of the Cosmo range hood was easy. They provided all the hardware needed to install the range and they included round and rectangle duct connector. They also included flexible duct hose to connect the range hood to the vent. I wish they had included the template with range. I was able to make template using cardboard in 10 minutes.
The range works really well. The fan has 3 speeds. Most of the time we are using it on 1st speed. On 3rd speed it does 500 CFM. However it is little too loud.
The LED white lights are really bright. Now we don't need extra light in the kitchen while cooking.
The filter are dishwasher safe. We wash them once a week.
Just got the hood. We put it in maybe a 1/2 an hour. Instructions and put in was easy. Very nice looking hood. We are using it as a Duckless hood. The fan seemed to work great. The only con was, it didn't come with a filter. They do offer you a free filter kit that you can send for.
I bought this a month ago, when our previous range hood of 35 years quit working. The lighting is great. I love the fact that the hood baffles can be put in the dishwasher for easy cleaning. It looks fantastic.
