Query: Worthless. Do not buy.

Had a pinhole leak in it brand new out of the bag. Filled it, drove to my camp, left it in the front passenger seat-well, and came back to find about half the water (2.5 gallons) had leaked out over 2+ days. Still working to get a slight mold/mildew smell out of my car. Don't take the risk with this product.
