I find it somewhat funny that I rate a soldering tin online, but it seems there still are small things in life that amaze me :) This Mundorf tin has a high amount of silver so I was doubtful about the ease of use. I have tried multiple tins with silver, most of which were unusable or extremely hard to work with. These need a bit more heat than your average tin (I have used 370C) but once it melts, it flows! And I mean even the silver plated wires will suck it in perfectly.
I found the best tin, I can honestly say. If you are into soldering and want the best quality, look no further.
