So far great, hope it lasts (instructions to install)
Everybody says that it is easy to install, but it was not obvious to me, so here is what I did. I positioned the adhesive with the protective plastic films against the body of the phone (in my case the thicker green plastic was in contact with the phone); then I peeled the larger clear protective plastic to expose the adhesive that faces the cover. I pushed the cover against the phone with the green plastic film in place. I pulled out again the cover and made sure the adhesive was correctly stuck on the cover by pushing around the cover on the green plastic film. Finally, I pulled the protective green plastic and put the cover back on the phone. While it looks perfect, I hope it lasts (If it doesn't I will be back).

Excellent
Works on my Galaxy S21 5G (SM-G991U) smartphone, which I purchased directly from T-Mobile. I was having constant problems with the phone's microphone, as well as intermittent charging problems, so I installed a replacement charging port.It took a little bit of patience, but there's plenty of how-to help on YouTube. I watched 3 or 4 videos to get different perspectives, then went to work. This was my first time tearing down a phone (and I'm well over 60), but I felt I had nothing to lose. I'm glad I did, and the replacement was a complete success.I installed this new seal for the back cover, since the old one was damaged beyond repair. Maybe I should have applied more heat, but I don't know. As I said, it was my first time. I was at least smart enough to have the new seal on-hand. Installing it was straight forward. Two were in the package, and I was successful with the first one. It's nice to have a second one, just in case.BTW, I used about 10 binder clips to clamp the back cover to the phone. Most of the advice was to add pressure for 10 minutes, to as much as an hour. I used the clamps for a couple hours, and just left it alone. Better safe than sorry.

It works great

If you use this carefully it works
The problem with this is you have no idea which side is which it's not marked at all. So I cannot tell. The quality of the glue is good. It sticks instantaneously. But functionally I wish they had marked which side is the top which side is the bottom and how to peel and apply it. But I got it going
