Not tried the shampoo, but the Pre anf foam are ok! Actually better than others I’ve tried! Sprayers when pumped up don't last long before re-pumping, but not a real problem, except when up a ladder cleaning the caravan roof! The teal problem I have is the continual emails I get, twice a day sometimes! This kind of Americanised marketing/sales is a complete turn off for me. If it doesn’t stop, I’ll close the account, as it really is annoying me!!!!
