First of all, we are talking about a cheap tool. When someone buys it, the first thing they need to do is replace the cable with rubber because its own is very small and it burns. It is a wrench, it has nuts up to 63 and easily fits with two worn ones, holding at 313 degrees without problems. After 3 months of work, the Allen screws need tightening and they don't need it again. Overall, it is a value for money tool and it still works for me (2 years with a boiler stopper f63, Plumbing f50 and some light conductors f50). It would be good for someone to choose it as a second one. The metal case is rubbish but... that's it!

Small. Lightweight and reliable.
upd after about 1 1/2 years, the thermostat gets stuck ....... it's lightweight, doesn't tire you out, it's small and helps you stick to tight places, but in the end, it's not reliable ....
