For the child, it is very good, a little difficult to inflate. In the first few days and as the days go by, the child gets used to it and finds it easy.
Now, for deflating, the only easy thing is that you simply hold the valve with two fingers and press it while pressing various points with the other hand, and the air escapes quickly. And the best part is when there is a little air left, you fold it down to remove the remaining air.
I bought it from a store in my city for 4.40, compared to what it costs here (after I found it), for my brother's child and he is completely satisfied and of course, he doesn't get off the JET SKI! He only gets off when he hears his parents' voice.
