The product is cheap and it doesn't work. It is supplied with drivers but although I loaded these (reluctantly) I still cannot get my PC to recognise the unit. There are no instructions supplied, that might have helped.
At least I did not waste much money on it. But my advice is, don't bother.

Hydrate 80 really works
Use regular paints over it though, not Hammerite which reacts with it.
