COSMOCOS-QB75 Under Cabinet 30 in. Range Hood with Push Button Controls, Permanent Filters, LED Lights, Convertible from Ducted to Ductless (Kit Not Included) in Stainless Steel (30 inch)

Nicest range hood I've ever had! I love the rounded corners; especially nice since this hood extends 22 inches out over the range. I figured I'd bump my head a lot since we had to install it 25" clearance over the range. But so far it's not been a problem. I like that the control panel goes dark when it's turned off. We have a great room floor plan, so having the LED clock blazing out the time all day and night can be annoying. Having a light on each side of the hood is like having a spotlight for each of the front burners (don't much use the back ones). But best of all is the great, wonderful CFM. It really clears out the steam and odors, I mean really, really clears them out. We replaced an over the range microwave, so maybe this is not surprising, but I can't remember any hood in any house (16!) I've ever had being as effective as this hood. I haven't had to use the highest setting, but the noise is fine on the lower settings. It is very heavy, so it took two of us using a cooler as a support to get it installed. The existing duct is 7 inches, so we bought an 8"x7" adapter which worked out well. The cabinet was already reinforced for the microwave, so all we had to do was enlarge the vent opening from a rectangle to a circle. All in all, straightforward to install but taking some strength and maneuvering in tight spaces. Hey, Cosmo, consider a bracket to support the bottom edge. That would be much more useful than the brackets that came with it.

The media could not be loaded.  This is going to be long review, but I think it is important if you are going install this yourself, that you read it.First, I recommend you take the time to research what kind of connection you currently have. Even if it means removing your current range hood and reinstalling it. You cannot do this half way if you want the great suction this fan is capable of.Second, this range hood is heavy. It is easily 3x as heavy as our old one. Our old one was not one of those white. 20 year old hoods either. This one needs at least 2 strong people and a third normal person to install, unless you have a jack.Lastly, buy/order the right kind of duct tape (foil kind) for attaching it. You do not want to do all the work of installing this and then hear it whistling or leak air.Okay, now let's talk about the width. You need to have 24in clearance between the stove top and the hood. This is much wider than my previous hood so we ended up being exactly at 24in after we installed it. This meant my 6 foot 3in husband loses sight of the food he's cooking when he is standing in front of the stove top and looking down. He said it is worth it since we will eventually be getting new cabinets in the next couple of years.When installing this range hood, the template that comes with it works great to mark the holes and make your pilot holes. Remember to account for any tile and move the template up a little. This range hood also had its holes closer in then our previous range hood so we had to add 1 1/4in plywood to the underside of the cabinet for the new screws to be attached to. This meant a trip to Ace, cutting two different pieces, gluing them together, then screwing them into the underside of the cabinet with more wood glue. This was for safety and for reassurance it wouldn't fall down on us while we were cooking a month from now. I personally would rather go beyond the standards then meet them.We originally had a rectangular ducting attachment but it was easy to remove the cover from inside the cabinet and disconnect the rectangular opening from the main vent. This was about a foot above from the new range hood vent. We did this before attaching the range hood to the underside of the cabinet so we would have plenty of room. The circular ducting that comes with the range hood fit perfectly to both sides of the range hood and the home ducting.The last part of the installation you should take into consideration is the plug connection this range hood comes with. Mine needed to be wired in, so I cut the plug off, strip the black covering back 5 inches, and made sure not to cut any of the cables inside. With the house power off, I attached them to my home connectors easily with a wire twist thing (don't know what they're called).Now about the product itself. I love the range. This range hood has two fans and a lot of power. It was less expensive on Amazon than the big box stores and is much nicer. It looks professional and the filters are so fancy looking.Overall, I came across more obstacles than I realized in changing out a range hood on my own, however, this was completely worth it. The noise is there when you have it on anything more than the first level, but I don't really care about noise when I'm cooking, I want the suction power and light. The light is very nice. I like having LED instead of halogen bulbs as well.This range hood is awesome and I'm so happy with it. Please just remember to ask for help because it is very heavy and you probably should have 3 people.Buy it and enjoy having a wonderful and beautiful range hood!

Pros- Very good suction, nice lights, quality , looks nice, Not overly hard to mount but heavy, no way to do it by yourself IMO or at least not carefully enough to not drop or risk scratching the new finish. Mine came with the large clamp for the duct and a template and accordian style duct.Cons- Mounting screws and hardware not adequate, screws need shoulders or built in washers. Trying to slip heavy hood over screws with the washers moving around is impossible, tapered wood screws are not made for this, the heads are barely bigger than the slots and could pull through easily.I was shocked that the whole hood did not have protective film BUT the grates had the protective film on both sides even the side you will never see "weird" kind of a pain to take it off of all the small grates. Nice and shiny though, to bad you will only see that side when you take them out to clean them.The plastic damper "ears" needs rubber grommets or something to stop them from rattling on higher speeds. (at least that is what I think is rattling). Funny though I didn't hear any vibration noise when I tested it before mounting.Mounting- I had to use most of my own screws etc to do this. I have a block wall so I TAPCON fastened to concrete on the back wall. On the top I drilled the holes and used countersunk bolts going down through cabinet bottom and nuts on inside of unit. No way I was going to trust the tiny screws that came with hood. Existing duct is 8 inches so that was nice and no restriction in flow. I used about 4-5 inches of the included flex-duct just because I didn't want to run to hardware store for a 4 inch piece of duct. Any longer and I would have and used normal rigid duct. Even with help, I rigged up a bottle jack with 2X4 on top of a 4' ladder to hold in place and jacked up slowly while we tightened the screws and nuts. Trying to get the top 2 tapcons into the concrete with a "stubby" screwdriver with no space was a nice workout on fore arms. If I can get rid of the rattle on 3-4 speed I will be a happy camper. All in all I would buy this again. For the price, looks and airflow it's a good deal.Edit: Bulbs just arrive and installed first two are with supplied bulbs second two are 3.5 watt 2700 daylight led bulbs. Just installed while cooking so judge for yourself it you like the more yellow color verses the blue that come with unit.
