Seems a lot for your money but I have never heard of them personally. I would invest in something more well known.
wouldnt go for it personally mate,
if youve got a CW one then the Werkstat Acryllic is the stuff you want, Polished Bliss do a kit,
good guys as well, always happy to take time and answer any questions you have.
forgot to say as well its incredibly easy to use,
Seal, Spray wax on, buff off, then maintain from there.
