COSMO COS-QS75 30 in. Haven Collection 500 CFM Ducted Under Cabinet Range Hood, Touch Controls, LED Lights, Stainless Steel

Everything was well packed, and delivered undamaged. We chose 36"x10" model, it comes with only 8" round duct, our ducting system is a 6" one. A short trip to Lowes to purchase 8 to 6 converter and everything wise went smoothly. The installation instruction says you need two people to install it, and they were right. It is very well made unit, and it is heavy. There is no way one person can install it.So far we are very please with the product. The only con is I wish the I could change the color of the led lights, we are not too crazy about the white light that it comes with. I think sometime in future I'll change those led lights to yellow leds.

Pros:- Stainless steel finish design that looks fantastic- LED light is bright with just two bulbs.- Noise level is not super silent/quiet, but with 500 CFM or higher I don't know if you can find one that is super quiet.- Smoke suction is really good and does the job.- Not super lightweight but for a dual fan appliance it was not that awkward to install.Cons:- The touch buttons on the control panel is hard to find in the dark. So, if I just wanted to turn on the LED lights from the range hood in the dark, it's not that easy. However, on the other hand I just kind of have a mental memory of where the button could be located on the control panel. I have been able to pretty much turn on the lights when I needed it.- The clock does not display while the fan is running for the range hood. Not a deal breaker, but just would have been nice to have more visual data to see while in use.- The back panel screws, the screws provided and instructed for the back of the range hood, are useless. It is the most confusing and difficult diagram to follow, from an otherwise pretty simple installation. The back screws are there to help hold the range hood while you screw in the top screws.- The screws that goes on the top are the weakest looking screws, but they do the job. They kind of just stick out straight from the top. So if you drill the screws upwards and they poke through the cabinet panel, there are four sharp screws sticking out. Very awkward. Would have been nice to have some kind of end-screw caps to cover them.Summary:I've been using this for a little bit more than a month and have been very impressed. Before this range hood, we had a microwave under the cabinet combo vent appliance. It was one of the worse smoke venting appliance I have ever experienced. The smell of scrambling eggs fills up the entire home. With this Cosmos COS-Q57530, cooking curry, steak and many other food items, the smoke do not go beyond the stove. I have had to use level 2 to cook and nothing higher. The noise level for level 2 fan is not super quiet, but it isn't that crazy either. I can't describe the noise level, but it is better than the over the range (or under the cabinet) microwave vent that was originally installed.Oh the timer to shut off the range hood is pretty awesome, I have learned to use that lately. If I cook something that smells pretty strong, I will set the timer to shut off 5+ minutes (you can configure it for 1 minute or higher). I can go eat and not worry about having to get back up to turn off the range hood.The installation diagram paper that they provided was pretty good, I had to ultimately ignore the back diagram because it just didn't make much sense. I drilled so many holes in the back of the wall and none of them matched up to the actual holes on the range hood. If they were required I would have been really angry. I used a small hand lift to raise the range hood up (don't buy the hand lift they sell here, it's a horrible design). The diagram hole for the power cord is accurate, so don't think drilling a smaller hole will work out (I found out the hard way).I had to widen or cut a circular shape hole since the over the range (under the cabinet) microwave vent had a square vent and Cosmos is a round 8 inch vent.It comes with a flexi-duct adapter, which I plan on replacing because I read that it is not recommended for safety/long term use. I can see that the creases from the flexi-duct could potentially catch grease and build up long term enough to potentially catch fire. Furthermore, the flexi-duct is not smooth, so air travel going through it may just cause more noise compared to a smooth/solid duct. My duct goes straight up in the ceiling so not difficult to swap out.Overall, I do recommend this range hood. I haven't had any issues (yet), but I have read where another customer had the fans stop working after a month or two...? I suppose we shall see, because the previous reviews seem to be good overall. If I run into any major issues, I'll be sure to add it to my review here in the future. I use my range hood every day for slightly over a month and have had no issues with it so far.Update 06/21/2021: Installed this last Oct 2020, and we have been using this on a daily basis (2-3 times per day). No issues up to this day. I have not had to turn the fan on past level 2 (out of maximum of level 4), as an example, for either steaks or curry cooking. Still need to get rid of my flexi-duct, but I have to go and find the right fitting.

We bought this hood because our over the oven microwave was not collecting the grease or venting well enough for the amount of cooking we do, & I’ll say that this is a very powerful hood that does a really great job, but-This was one of the hardest installs I’ve ever done in my life & I installed some complicated things before. I’ve worked as a plumber, electrician, carpenter, welder, general contractor, & this was not easy. In all fairness, it wasn’t just because of this particular product but also because we live in an older house that needed a lot of modifications to fit this hood. But to address the problems with the install of the product to help future buyers?The hardware kit it came with was useless to us. It might be good for you, but the Sheetrock anchors it came with were too long for us, so they didn’t catch & the screws provided easily moved in & out of the anchor which made it much harder to hang the hood. The screws to mount under the cabinet? Are VERY hard to get to, where I had to use a 12” x 1/4” drive extension on my impact wrench just to get up there, and that made it impossible for a one person job. So unless you can build a rolling mount that you can sit this on, & roll it into position? Just know you’ll need an additional person to hold this up while mounting it. I personally cut some 2x4 pieces to go into the cabinet so the screws had something thicker to bite into instead of the 1/4” MDF board the cabinet was made out of, & I had to use my own screws that were 2 1/2” long to make sure it was secured properly. The template needs to be measured up to the hood so you can see where the screws need to be placed & what part of the template needs to be cut off. The template itself was very flimsy & bent so two screws didn’t line up correctly on the wall. Maybe if it was a little thicker & not folded in the box?If your vent is set up for a 6” system? You’ll need a reducer from 8” to 6” because this is an 8” exhaust. Which I had 6” flex pipe that I feel should be made 1/8” bigger to ensure an easier fit. And lastly, once you have it mounted secured enough, & you’re moving on to work on the vent connection? I would have that person helping you, start taking off the static protective plastic from the baffles while you get everything finished. Nothing worse than thinking you’re done, just to find out you have another 30min of peeling off film.Ok, now for the good stuff. It’s a very beautiful hood once everything is installed. The baffles make the hood look like a commercial grade kitchen that you know will be easy to clean because they are dishwasher safe. The fan is SUPER powerful & I know many complained about the loudness, but the fan on my microwave that wasn’t sucking up any air was equally as loud. Also, if you have a gas stove I’d highly recommend getting a strong exhaust simply because of that reason. The LED lights are very bright & pretty when they are on vs our other which had a dark yellowish tint from the built up grease over the light fixture. I only wish they included a kitchen timer in mount for when the one on the stove is being used for one dish? You could’ve had that for a second.Overall, we love this purchase but just wish they redesigned it so that the mounting screws were a little better accessed & because of that? We feel the price should’ve been a little more reasonable. But we are ultimately happier with this than what we had.Hope you have an easier time than we did installing it, & you love yours as much as we love ours.
