I have seen feedback on muggyweld and I call it like it is, this stuff works well "WHEN YOU FOLLOW PRECISE DIRECTIONS!!!" It will take some trial and error and took me two rods of fiddling before I got it down but as an avid builder I have found it to be quite useful in a ton of situations if you want $8000 dollar tig weld results well go ahead and buy one but for the money and for specific uses I've found it to be invaluable stuff around my shop. If you have any concerns of it's strength try grinding it off if your puddle gets too large lol. When it's on there it's on there!!!
