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

After reading reviews about installation I felt confident in my abilities to install. The hood is a good sized hood and it did take me 3 people to install it. For anyone looking at installing it themselves, I offer up these considerations before starting.1) I hoped maybe I could get away with only mounting it with 4 screws to the underside of cabinet. Once I got it open and lifted the unit and re-read the directions, I realized it needed to be installed to wall and under cabinet for my application.2) I needed to remove (4) 3" tiles from my backsplash in order to mount the 4 screws to the wall. I had the tools to do it and could not tell until I removed my old hood that it needed to be done. The template they supplied help Identify with 4 tiles to remove.3) I read other reviews and found it common to install the 8” duct to a 6” exit duct via a reducer duct found at my hardware store. That was an easy job, again just a little time and tape etc.4) I installed the 4 of the (hammer in) screw mollies supplied in box. Lifting the unit into place and attaching to the wall was a task and I used stacked boxes to hold it near the position until we were ready to lift and attach. (Use boxes that allow access to all the screw holes on rear and upper holes.) Once we installed the 4 rear screws slightly tight, we adjusted the elevation with more boxes until it was tight up against upper cabinet. We then installed the 4 upper screws that pulled the hood up tight. Once installed on upper cabinet, we tightened the rear screws.5) Now the electric hookup. I had a hard wired hood and this unit had a plug. Some reviews had people cut the plug and wire it into a junction box. Instead I installed an outlet in the upper cabinet area where the ducting came up. Again, I have experience in that so it was just a couple dollars and more time. Plugged in the fan and it worked.6) Ducting install was pretty effortless. I installed the 6” portion of the 8”-6” reducer to my existing duct. Had to tweak and bend to make it fit but eventually taped it in place. I used the flex duct supplied with the unit to connect hood to the 8” duct reducer. Easy!7) Loudness. The unit is loud but every review said that. I wanted good suction and moving air makes noise. Even at low setting it makes a lot of noise.8) What I didn’t really anticipate is the size of the unit. It sticks out from the wall enough to encompass my whole range, love it. I ended up having the minimum height from range to hood per their spec. I’m 6’ tall and it is easy to smack my head or turn on touch sensitive buttons on the front of the hood if I’m not careful. Gotten used to it now though and I’m good. My plan was to remodel the kitchen in a few years and use this hood when I do. I will fix some of these issues then.9) I give this unit 5 stars so far. I think I’ll like the baffled, removable, washable filters. I hated my screen on the last hood. It was always greasy and dirty looking. I will remodel with an 8” duct instead of a reducer as it may be contributing to more noise and less evacuation but for now, it works great.

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.
