Anyone used this freezing kit?

[Bogart]

Looking for a cheap freezing kit and came across this for the money looks good. Have used in the past the arctic where one measures out the freeze spray by means of a balance this looks a lot simpler. I just need it for the odd times I may need to shut off a rad or tap.
