Review: 🔥🔥🔥 super
Review: Great solder. I was put onto this from joey does tech YouTube affiliate link as the solder i was using was a AliExpress special that was supposed to be lead but did have that sine to it or didn't flow like lead solder. This is about 4 times the cost of said ali solder but man this stuff is worth it. As a weekend solder-er i was trying to do things on the cheap but honestly this is one of them buy once cry once kind of things this is so much easier to use. It's not that expensive relatively speaking but it feels a lot compared to others. You get a 100g on the reel, the size i bought is 0.3mm and is fine for the small smd stuff i am doing at the moment and mods. 10/10 will buy again and get some larger stuff.

Perfect for solid joints without the hassle. If you're looking for dependable, pro-grade solder, this stuff delivers. Its always better to spend the extra money on better solder products cause it just makes the job easier.
