Couldn't be happier with our purchase! These are best used in warm weather/water and plan on getting more than a little wet. I rated 9 due to the fact that the kids will get wet, both from paddling drippage and the drain ports in the kayak allow a little water to be present in the lowest areas of the "cockpit". My kids paddled and paddled and couldn't get enough. The kayaks are easy to learn and VERY stable. We had a couple of times where the kids needed a little snack break and would come enter our canoe, snack, and head back out. No tipping, easy to use. Thanks Lifetime, for a great product.
