I wonder if this really works.

Apparently no more sweating copper pipes. Any thoughts or someone that has actually used it.

I have seen it and first thought was that I didn't trust it, but their information says otherwise.

I didn't see any code approvals.  

I can't use copper here as our ground and water eats holes in it in a few years so no recent experience..  I did several houses soldered in the valley years ago.
