Review on 🔌 Monoprice Cat5E RJ-45 Toolless Keystone Jack in Sleek Black: A User-Friendly Networking Solution by Domonic Roberts

Not a bad product if you don't have a hammer drill. If it came with instructions it might help. I had to uninstall and reinstall them for them to work. I'd say you're better off getting a long-term punch tool if you have a lot of these to install. If you only need 1 or 2, this should work just fine. Just be patient with them. Be sure to insert the copper as far as possible before lowering the clamp. That should help a lot.
