I bought this for my daughter's 15th birthday. The kids loved it! I ordered the whole set of 8 to make a whole Pizza. The package contained 8 individually packaged slices. Each slice has 2 valves. They inflated easily and also tied easily together with pre-attached bungee cord and plastic ball. No downsides. The only thing to be aware of is the giant size. It's easily 14 feet in diameter. Make sure it fits in your pool. After the party we deflated and stored 6 slices and are now just using two. They are some of the best pool floats we ever had. They have cup holders and a head rest. easy to get on.
