⭐ 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 👍

Not 50g as stated only 44g, but Its good enough value for your money at £6.89
Not 50g as stated only 44g, only 6g missing you may think that is not much well that's 1.9m or 1900mm or for non metric just under 75 inches. That is a lot of solder, the thickness is mostly consistent 0.8mm. I have found a temp of 360c to be fine and fast for my needs. It is a easy to use, easy to clean solder and function's well for my needs. Its good enough value for your money at £6.89 and does what you require, just a shame the weight is not accurate.

Quality & Value
Good quality solder wire that is easy to use. Unlike similar listings, this roll of solder states the weight of the solder wire excluding the plastic bobbin. Highly recommended.

Great solder
The solder that came with the soldering iron was rubbish - didn't flow for toffee. This, though, is a different can of worms - does a really good job of it.
