More solder than I will ever need
This solder works. It looks like chinesse crap but it works. I even unspooled the whole thing to make sure they didn't weigh down the spool to make it feel heavier, but it's legit and now I need to try and fix it.

great adhesion to wire
good size and quality. I like the fact that is lead free and great adhesion to wire without dripping everywhere.

Really thin
I didn't know what I needed. I was soldering wire into a terminal and thought this would do the trick. This is really thin and I used up a ton of it trying to get the terminal filled so I could put the copper wire into it. Just know that this is really thin and probably made for some precision use.

It's Solder
Rosin core solder, it's great what more can you ask for. Used it in fixing a bunch of gameboy cartridges and more with no issues.

Works great, even without flux
We were having trouble getting our soldering joints to stick together until we tried this solder with a torch. It worked great for soldering the joints in our silver plated jewelry pieces.

Good stuff
Basic solder. Flows nice melts clean little crap buildup. Little light on the flux but nothing inhibiting and I’m guessing that’s why it flows like it does and still stays a clean solder.

Esta muy bien, al fundirse casi no suelta humo y cala a comparación de las que tienen plomo y al tener el flux se facilita a la hora de soldar
