I'd rather have to look earlier in electric forums and squandered money rather just invested in these! Weller and Ersa are in fact the only ones that are recommended there, and sometimes especially this one!
I often solder around with boards of old amplifiers or consoles. With the old, it was pure luck that I got out the parts and not been nasty the board. Solder also never stayed at the top. and the warm-up phase took his already 2-3 minutes! and the hottest point, so that the solder was melted never on the actual top.
These soldering irons makes it even fun right! Fine work is possible without any problems! A warm-up time of less than 20 seconds is given! And it is a solid continuous tip!
Would recommend this flask to anyone who has not a great deal soldered.
