"Great quality flux & decent quantity too. Have used other fluxes but this one is my personal favourite. Would choose it over any other flux on the market, soldering jobs are clean & tidy upon completion & any excess is easily cleaned off pipe work. It is pretty powerful so be sure to clean off any excess or your nice copper pipe will turn green very quickly!"
"I changed to this flux when my existing tin (circa 1985) of fluxite ran out. Suddenly all my pipe joints leaked. Pulling some of them apart I found that the solder had barely run. My opinion is that is flux is useless."
