I purchased 5 of these tubes for my grandchildren for Xmas. All went flat during the first use. We live in Vermont and had lots of snow so tubes weren't used on surfaces that may have cause damage. There were no visible holes - the tubes just leaked air. Very disappointing. Should have bought the cheapest that I could find - they couldn't have performed any worse. Don't waste your money on this product.
- Please tell us about the quality of the product. Very poor
- Was the product free of any manufacturer defects? Don't know
