I have it, I have used it. I do see both advantages and disadvantages to just for copper.
advantage if you can't sweat copper than this product is a god send. Also, if you can't safely sweat a pipe i.e. a joist is too close or you can't get the heat close enough this product works great. My reason for buying it was example two.
disadvantages: if you don't put enough product on both ends when glueing the pipes together IT WILL LEAK, it happend to me first time using it.
If it does leak there is only one way to stop it from leaking cut out that section and replace that section hence more cutting and glueing. You just can't add more bonding agent to the fitting and hope it will seal.
Then there is the drying time.you can't move or touch the fitting after 5 seconds and cant move the area for 8-10 mins PER fitting. so if you have a lot of fittings to do it WILL take you all freaking day long.
with sweating a pipe you can re-heat the pipe to redo the fitting.
This product will bond more than JUST copper. read the instructions to find out exactly what it will bond too.
Like I said I have it and have used it. It works great as long as you follow the instructions. I have a few fittings that I did acctually use it on and they have not leaked in over three years.
