Seen my mate use it
Does work very well, slightly better than the menzerna if used with the right pad combo. Use the wrong pad and buffer trails galore, although very easy to correct with a lower pad.
Very very very dusty though, worse than autoglym to give you an idea!!
Slightly more effort needed due to the dust although the finish is worth the mess....
I was impressed with it, although not convinced enough over the menzerna
