Query: Don't waste your money

Don't waste your money on this piece of junk. Not only did mine fail in a moderate rainstorm, but I have yet to meet anyone who has had success with an "ace-in-the-hole". The pump is weak and does not have enough strength to clear out the pit from possible damaging stormwater. I had to hand-bail my pit. The battery was fully charged as well. This company should be prosecuted for marketing their product as they do. It's a joke.
