Hi Stuart
sorry for the delay, yes ive got one of Andrews Pure Freedom trolley's its an excellent bit of kit. When you get yours you will not regret buying it one bit it does everything it says it will. Andrew is very helpful with advice and backup service, i only purchased the trolley and pole from Andrew i got my ro from Ro-Man. I've produced a lot of water from my ro and i havent had to change the resin.
Probably work out better if you get the whole package from Andrew, i live in Nottingham if you live near by you are quite welcome to come and see the trolley working. Its been the best move ive made into wfp
regards
Brett
