Works as Wriitten its actually amazing and didnt expect the results too be so good
Telling you what as in for not leaking and Fast clean hold.. This stuff is amazing .. bending the pipe back and forth under pressure yeah it will break but any mechanic and plumber knows compare it too locktight if you twist it enough or bend it it will break loose but a copper pipe in the wall or for a fix its as good as solder its amazing actually i never believed it would work... for the price and the big bottle you can do allot allot of pipe repairs for allot less money for solder and Map gas so a better value for the money for sure

Solid Connections
I had some pieces of 1/2" copper left from a project and wanted to build a plant stand. I needed it to be secure and strong so I could pick it up and move it around and not worry about it coming apart. This worked great! I tried to pull the pieces apart and it is solid. So easy to use! I also purchased a similar one from my local Ace Hardware but this one was about 4x as big and cheaper and this one worked at least as well if not better.
