TOWOT 63-37 High Purity Tin Lead Rosin Core Solder Wire for Electrical Soldering, Content 1.8% Solder flux (1.0mm, 50g)

Flows SO well. Melts like butter. Nothing else to say. It's quality stuff and does the job.

Having been burned by a bad roll ( or three) of bootleg solder before, I had serious doubts about this brand. I'd purchased several cheap rolls from...a famous Chinese marketplace, and just shelved them until I needed them. Well, I'm pretty sure they just used old fishing weights to make the stuff, because no amount of flux or heat would make that junk stick to pads. THIS brand – I'm happy to report – is quite the opposite in terms of quality and performance.This acted as I expect decent solder to act, and wasn't unlike the old roll of Radio Shack solder I just used up not long before buying this. I can't speak to using it without extra flux, but with my (likely knockoff) Amtech flux it wets great and cools fast to a nice shiny ball. And the price for a 100G roll is good.If you need like a pound of solder, sure, get the Kester 44, it'll have a better cost-per-amount and be top-notch. But for small-time hobbyists like myself, this is just fine and WILL be a dependable and cost-effective option. Not even a little disappointed, quite happy with this brand.

This is a fantastic solder wire. It melts smoothly, creates strong joints, and the rosin core works great. I've used it for several projects and it's very reliable. Definitely a good choice for electrical soldering

Good solder, melts very easily, it's very thick, got it for assembling rc cars and it worked really well. Easy to use just unwrap and if you want, cut however much you need.

Good quality solder that flows smoothly. Works well for electronics projects, though the spool could be a bit sturdier.

This Solder made my life so much easier, I was trying to solder the wire on a stereo so I don't have to worry about the wires coming undone and it wasn't working with the cheap stuff that I had. So I looked at the reviews of this product and the stuff lives up to the reviews. defiantly will be recommending to others. clean up was easy. The size of the solder perfect for the application i used it for. It wasn't to thick and it dried fast enough to where is didn't get sticky on my work area. great product.

I bought this solder to use for XLR and other audio connections on microphones and cables. It worked well for my purposes.

Great 63-37 for electronics repair.
