Solar fountain (Aspley NG8)

Not working properly. Amur brand frog fountain (says for bird bath, but it's quite big). Bronze colour frog on stone is a good size, but not a real stone of course. Pretty much unused, as it didn't work properly but I didn't manage to return it to Amazon for a refund. PLEASE NOTE: NOT IN PROPER WORKING ORDER. From memory, it seemed the pump didn't work correctly. It worked ok for a short time but would then stop working. I don't think the problem was the solar panel because I fitted that to something else and it seemed to work fine. Probably not hard to repair or replace pump if that's the issue. Please say when you could collect.
