Nice Flux
Best rosin flux I've ever used. Makes the solder flow nicely, and no stinky smell.

great product, leaked in shipping
This is a great product. lid was almost off. Minimal leakage during shipping, otherwise I would have given it five stars. Both application brushes were sticky from the leakage, but a nice bonus. If it wasn't for the retaining seal, this would have been a big mess. Will reorder when time comes.

Same as all the rest
I went and bought this thinking it was better than other other brand, but they’re all the same. It does what it’s supposed to know better or worse than any other one I’ve ever had.
