Just What The HDMI Port Ordered
I was replacing an HDMI port on a PlayStation 5, and I kept fighting the solder I was using. I was told I needed leaded solder with the particular specifications this solder has. It worked perfectly. Nice bright shiny solder joints, and it seems like they hold very well. Makes soldering a breeze and cuts down on the time to get the repairs done. Great solder for a great price. Photo to show you that this solder is great for putting out any dumpster fire that lands on your work table. LoL

Good solder for battery packs and tinkering with electronics
If you've soldered enough, you can tell the good stuff from the bad stuff. This is the good stuff. I keep my soldering iron at about 740 F and I've had zero issues with using this solder. It spreads well and forms a strong bond with the materials you ware working with. I've purchased this brand solder several times and have been happy with.

Excellent product
Excellent value for money, it contains plenty of solder, enough for several large projects, and the quality is very good. I haven't needed any cleaning paste so far to achieve a firm and even solder joint.

Smooth, Clean, and Reliable — Excellent Solder Wire for Precision Work!
This High Purity Tin Lead Rosin Core Solder Wire is absolutely top-notch and performs far better than most generic brands I’ve used. The composition is perfectly balanced, offering great flow and strong bonding on all types of electrical connections. The solder melts evenly and quickly, which makes it very easy to control during detailed work on circuit boards, connectors, and fine wiring. The rosin core is high quality and provides just the right amount of flux enough to ensure clean joints without excessive smoke or residue. Each connection comes out shiny, solid, and professional looking, with excellent electrical conductivity. It adheres well to copper, brass, and tinned surfaces, which saves time and eliminates the frustration of cold or brittle joints. Another thing I love is how consistent and smooth the wire feeds. It doesn’t splatter, drip, or give off harsh fumes like some cheaper alternatives. The wire’s purity and consistency really stand out, making it ideal for electronics repair, PCB assembly, hobby projects, or general electrical soldering. In short, this solder wire delivers reliable performance, clean results, and great value. If you care about quality and want professional-grade results every time, this is definitely the solder to keep on your bench.

Not Kester, but I bet you couldn’t tell the difference!
Quality solder, consistent alloy mix, and very little if any impurities. I’m actually quite surprised at the quality of this alloy at this price point. It’s not Kester, but I’d bet 99% people using it wouldn’t know the difference when being used for most applications. So unless you work at NASA or BAE, you’ll be happy with it. Good stuff

Un fil à souder de qualité facilite vraiment le travail de soudage. Il fond plus facilement, s'étale et s'accroche parfaitement
