Review on 🔥 Hakko 557V V12 200W Matchless Soldering: Unbeatable Performance for Precision Work by Mark Tarnowski

The Hakko I received works perfectly. I like the on/off button. On first use it really smoked a lot; slightly less smoke on second use; and no smoke on the third use. Warms well and marks the wood. The only reason I gave it a three was because it's not UL rated. It doesn't really have a rating, which worries me because it doesn't necessarily conform to any standards or codes set in the US.
