Not fit for purpose

This product is useless, it burns off immediately and is unusable. I wish I had seen the other reviews before purchasing in store. Avoid at all costs, buy a decent flux and save yourself time and money.
Flat out doesn't work.

I had a small hard soldering job to do. I went to my local B&Q and bought GoSystem branded solder, blowtorch and gas tank, and this flux.
Even using the lowest possible heat on the torch and holding it a good distance from the solder join causes the flux to burn up before it gets anywhere near melting. The other items explicitly say they work with this flux but it just isn't remotely usable. After several attempts and having to clean the charred remains off the solder surface each time I've given up and just bought another brand.

I bought this yesterday to use with some yorkshire couplings and thought I'd give it a go as the go system torches are good. But after failing to seal a single fitting, buring the flux every time before getting to solder to run I thought it was just me as it was my first attempt at it. But no, tried a new flux today with the same fittings and presto every single one looked exactly as it should and sealed.

Worse than useless

Worse than no flux at all. Burns off before the pipes get hot enough for the solder to run, and then prevents the solder from sticking. Takes ages to remove the charred remains of it from your pipes, and makes soldering completely impossible! Avoid at ANY cost!

Don't waste your money, this flux actually cost me extra money and stress.
Appears to burn off immediately not allowing the solder to run into the joint (and no i didn't over heat it).
Eventually gave up and bought some La-Co flux and all worked as it should.
