i am buying a trolly this week , and have narrowed it down to two that suit me , i want one that just holds standard 25 litre barrels , so one empty can be swopped with a full one , with the minimum of fuss , so the WATER GENIE from cleaning wharehouse , or the PURE FREEDOM trolly from errr pure freedom , both are 500 pound ish , and i llike the look of both so any good or bad storys about either trolly , pumps breaking , battery life etc ....thanx gang
