I bought one on ebay and it only worked for about three weeks before it broke and would no longer pump water. \r\n\r\nI contacted the seller and he said he owed me nothing, since he couldn't confirm whether I was using it right or not. I assure you, I was using it right.\r\n\r\nIt was fine while it lasted, but it lasted less than a month. I'd say steer clear.
