⭐ Rating: 4/5 Good quality solder, melts quickly and flows nicely so it’s easy to get clean joints even if you’re not a pro. The flux core helps it stick properly and makes the whole process smoother, especially for small electronics work. Doesn’t spit or smoke too much either which is a bonus. Only downside is it can run a bit fast if you’re not careful and cheaper brands do a similar job for basic stuff, but overall it’s reliable and does what you need 👍
