Awesome piece of hardware for professional installation
Wow this was a pain in the butt to install, but it works and looks amazing! I live in a condo and can't change the look of the outside of my front door, so this was the only feasible alternative to those cheap sliding foam door sweeps. The construction feels very solid and the mechanism is smooth - no one knows it's there unless I point it out. Just keep in mind you need a solid door and professional tools. A local woodworking shop crafted a jig and routed it; a metal chop saw worked well to trim it a small amount to fit in a 35-7/8" with end plates. Another thing to keep in mind is that it can clearly handle angles/slants in the frame no problem, but can't seal gaps caused by waves, divots, or similar, curved imperfections. The drop adjustment was easy, but no way of knowing if it will stay put over time. If anything changes, I'll update this review.

Missing gasket: product ineffective
Despite arriving sealed and new-in-packaging, the product is missing a very important piece: the gasket (see pictures). The product listing shows the gasket, as seen highlighted in red in first attached photo. However, upon receiving the sealed, unopened product, it did not contain this part. As such, its ability to create an air seal between faces of the door is entirely compromised, as well as any “soundproofing” capabilities. In reviews for other similar products (different lengths) by same manufacturer I am now seeing similar complaints about the same part missing. It’s upsetting to see that after several years, these products are still being sold without the shown parts from the listing. Update: I contacted the manufacturer, to which they seemed very surprised (though I'm unsure how, as this issue has been reported in the reviews of these products since at least 2019). They told me order replacement through Amazon. I received the replacement, which like its predecessor, is also missing the same gasket/seal. I will contact the company again and will update this review if the issue is addressed. Until then, it's a safe assumption the entire batch is missing this critical part.

Cool product but it won't stop drafts
I've just received this and I'm really disappointed. I wanted it to be as awesome as it looks but I can't see how it will stop drafts. Once the door is closed and the metal bar the neoprene seal is attached to gets pushed down, the draft from outside will just go up and over the bar. There's a tiny seal at the top of that metal bar but once the bar is pushed down the seal doesn't make contact with anything. I even called the manufacturer but they weren't able to convince me that it would work for me, so I'm returning it. I'm giving this product three stars instead of zero because I love the hidden aspect of the design. If they could just add effective seals that will work when the door is closed it will be a five-star product.

Returned without installlibg
Decided to return. The piece I received was very hard to actuate and I assumed this was a defective unit due to the amount of pressure needed to actuate the seal.
