So - this tool was bought as a backup for famous "Leister" foil welder - and boy, were we surprised! Its absolutely same tool for like 25% of the price. We already have several sessions with this tool, where it ran non stop for 6-8 hours every day. No hiccups, no issues, just welding, welding welding. Welds are of good quality (but as its just hot air - there cant really be difference to another tool. Temperature knob works as expected - everything is really absolutely OK. Also the rolling wheels are of a good quality - and came free with the tool. Check how utterly expensive are those brand ones. So for me -this tool is small "surprise of the year". Absolutely must buy if You need it - doesnt matter if one time small job or some regular work.
