May Contain Lead
I don't actually have a problem with the product so much as I have a problem with the way it's advertised on Amazon + the fact it's listed in the first place.It mentions that it may contain lead on the package, but not on the Amazon listing. Lead can cause cancer or lead poisoning, which is obviously a major issue. This is precisely why the packaging states it's for commercial usage (what business buys their Flux, which they're likely to be using lots of if they require it, from Amazon?), but again, this isn't listed on the Amazon listing. People at home trying to fix an old electronical device in need of some Flux shouldn't need to worry about presence of materials that could give them cancer.

Very impressed
I was struggling to solder a smd resistor so gave this a try and it worked great just like in the YouTube videos, I used a 14G needle but would not advise going lower diameter as the flux is a little thick and will be hard to push out

Not so good, requires extra heat
I normally use nc-559-asm for computer and laptop repairs, but this particular brand requires a lot more heat for the solder to attach, therefore killing a couple of important chips.I'll stick to my previous brand, thanks.
