I've only used it a few times mate, seems fine so far.That's the one I've been looking at, have you used it? If so, how'd you find it? Can it just be used with water/shampoo or does it need lube?
I just use a mix of snow foam and shampoo, but I'm no detailer.
I'm sure people like @Scrooge and @yellowdave will be able to give you better advice than me. [emoji2]
