Sauro B.: Per ora a benissimo

Dale P.: Works very well

R B.: I did have to "adjust" the spring closers a bit, they were too strong for the hood fan I am using it with. That of course is better than being too weak, which I could have not done anything with! It is working very well. and that is a very good thing, as it is really hard to get to, it is at the far end of a very tight attic space and I insulated, the whole exhaust pipe to prevent as much condensation as possible. I don't ever want to go back to "fix it"!

RegularJoe: When my contractor put in my new rangehood, they didn’t put in a draft blocker because the range didn’t come with one. So I did this myself and it was super easy and therefore I am immensely impressed. It seems to work as I don’t get any Backdraft and my house is no longer losing a lot of extra heat.

Doug Bryant need to add more issues about buying this toy. Amazon has yet to respon to me about my problem of a refund. It has been over a week and NO response to me refund. WHY ?????: Part of a three piece instilled job.

Jeremy S.: Product works well. This is the second one I bought and replaced all the plastics ones I bought in the past that sometimes get stuck allowing cold air back in. Highly recommend

Tim: When I received the damper module itself, the dampers were warped a bit so it didn't make good contact against the seal. Was able to mostly get it back to shape but not like it should be.

Scott: Had a bathroom exhaust fan flapper that made crazy amounts of noise when windy outside. I took that dampener off right at the fan and went outside to install this metal dampener right at the output under the fascia. The bird screen was the same tube size so a little duck tape and reattaching the flex duct to the dampener did the trick. Since then, haven't had an issue with sound. There's still a small amount of chilly air that comes back but much better than the previous setup. Other users tried using tape to seal the center and I tried when I bought it too, however I failed at that and just installed as is. So far so good 1 month after install during the middle of winter.

Pipermom: Living in the deep south, after installing a new kitchen exhaust fan the down-draft from the attic was overwhelming. Especially since kitchen exhaust fans are located right over the stove and it is canning season! This item is wonderful. There is no more down-draft at all and combined with my wonderful new exhaust fan my kitchen is comfortable again. At least as comfortable as it can be when I am canning in the summer time in the deep south ;) Great product, shipping time was fast, installation was easy. Thank you!
