Review: Does what it was made to do - Tried this for the first time yesterday have to say this work really well. Didn’t heat up at all where you use it. Genius creation.
Review: 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.
