Best stuff ever for desoldering
This stuff is great. It allowed me to desolder and solder a hose bib to my piping without desoldering the nearby elbows. Wish I had it before my previous plumbing repair which resulted in opening a wall to re-solder the joint that separated due to too much heat conducted from the fitting I was desoldering.

Works as shown
This stuff is fantastic. I can literally cherry the copper with my hand holding the line right on the other side of this putty. Leaves very minimal residue unlike Viper wet rag which leaves a nasty mess.

Mine arrived dry and crumbly...only got to use once.
Maybe mine was just old but it arrived very dry. I added water to get it to a usable condition but once put on and exposed to heat dried up and flaked off. Not usable a second time.Kind of a waste of money if you ask me. Would definitely not buy again.

works but messy
leaves a mess, you end up getting a wet rag to clean the crap left over, nice idea but needs to be a clean way.

Retains shape on copper pipe without failing.
Excellent product for Heat Absorption. Takes direct heat/flame as well without ruining the putty.Sticks to the copper pipe even with direct flame and doesn’t break apart or fall off

It’s ok
It works ok but it don’t mold to the pipe like it should and it gets dry pretty quickly
