I have this thing now the third season in operation. Has tasted just nervous. The assembly proved to be an adventure. The holes for the screws were completely displaced and require rework. Then the next surprise, the water splashed everywhere, not only in the containers provided. The problem lies be solved by a small piece of tubing. After all, even better than an elaborate returning to England. Last year, on time after the warranty then the solar module has passed. So I bought an external module with pump and moved the cables are concealed. I come but when cleaning times on my little plastic tube, already field tested the wells again the lawn. For people with craftsmanship of this device is possibly a useful pastime. For the faint of heart, it is rather an impertinence.
