Review: Melts/sticks and flows like a champ! - This stuff works great! Smooth and easy as it should be. I had ran out of my normal solder and used a roll of Kester from work. Nothing would stick or flow right using that. I’ve been soldering hobby projects for years. The Weller solder got me right back in the zone. Life’s too short to struggle w/ bad solder. Just buy it. It’s good…
