The product took a little longer than others you may fit here of the same quality (it came from Vevor), but it was known at the time of purchase. Don't do what I did and wait until the last minute to order it for your project. It worked out well for me as I simply capped all my in-floor heating lines and pressurized them for the pouring of my floor, then added the manifold when it came in. As for the product, it appears to be of good quality. I had no issues installing it and have never done an in-floor heating system before. I have not used it yet with liquid to actually heat the floor, but it holds air (I used 40PSI to test and held 20PSI for a month). I'm not sure if I can come back to this once I have used it, but I will try to revisit my review after, if there are any issues.
