No relation to the Weller dogs we all know! In the second month, it rusted and broke (without any particular pressure) the plastic support of the heating part, and I had to glue it and fill the gap with high-temperature glue as much as it could withstand. The tip is stabilized with a very small screw, which no matter how much you tighten it after the first year, the tip will have some play and will greatly hinder you in delicate soldering. The original tips (about 15 euros) thankfully last quite a bit. If it didn't have the brand on it, I would say it's 100% Chinese. Prefer Antex or something else. It's not worth the 140 euros at all.
