I don't know who made the decision to put a sticker directly on the solder, but it was a bad idea. I think they were trying to hold the end of the solder in place on the roll, but solder holds its shape anyway. The whole roll was also shrink wrapped.I'll revise my review if I figure out an easy way to get the sticker residue off, but... Really?

This is a medium sized roll of classic rosin core leaded solder. This solder isn't used commonly in commercial applications anymore, because everyone has switched to RoHS (Reduction of Hazardous Substances) lead-free formulations. But sometimes you need to make repairs to vintage electronics or old projects without mixing solder types, and this is great for that purpose. The .032" diameter is a good medium size to stock that's appropriate for small electronics work while still being usable for larger soldering if you need to work on bigger projects.Leaded solder comes in two formulations, 60/40 and 63/37. I far, far prefer 63/37: that alloy is 'eutectic', which means it goes immediately between liquid and solid, melting and solidifying at the same temperature. That makes it much more predictable and reliable to work with. If you have the choice, I definitely recommend you choose this formula instead of 60/40.AIM is a very reliable manufacturer of solder and I've used their products for years. Once upon a time, I would have said that beginners in soldering should stick with leaded solder like this product because it's easier to work with, but I've changed my opinion - a lead-free formulation called SN100C is available from AIM that's also an eutectic alloy and just as easy to work with as classic leaded formulations. So if you're just looking for generic solder to keep on hand, consider splurging for SN100C to keep yourself safe from lead while doing hobby or small-batch production work. But if you need leaded, this works well.

I've purchased my fair share of much less expensive solder; some was ok and some I abandoned after using just a few times. I no longer gamble on the quality of the solder purchased and stick to brands like Aim, Kester, or MG. I like the 63/37 a little better than the old standby 60/40 because the 63/37 is eutectic, meaning it solidifies very quickly without going through that "slush" stage that 60/40 goes through when it starts to solidify. You get better solder joints because there's less chance of the parts moving around while the solder is cooling, which can result in a poor solder joint.
