I have used it and it seems to work well for my needs. You need to get it hot enough to be able to work with it. I could not get my propane torch to heat it enough to do anything with it. An oxygen/acetylene torch will do the job.
i'd like to try it out, but i really don't have the need for a full pound like they want you to order on their website. i'd only need a couple rods, maybe 5? anybody have extra laying around? shoot me a PM...
Used it today and it was ok. Did use it on the tin can and it works excellent for that lol. Had to buy a mapp gas setup because propane WON'T work. propane works great on the can.
