Great quality product.
There is definitely a noticible difference in quality between this and borax detergeant. However, for most applications borax works just fine. This works better for stubborn joints.

Makes a great paste flux.
I wish I would've found this a long time ago! I bought 2 other kinds of borax and neither would breakdown into a paste like this one.

Good quality, but you can go to your local hardware stores and get the same thing at a better price and more poundage.
