The first summer they survived.
At the 2nd summer in Tunisia is unfortunately burst out of the blue, so I was a water-filled mattress from the sea tow (to the beach then find the hole and let out the water again)
Very dangerous in my opinion, when children play with it, because the mattress is immediately set as a whole chamber has flaked.
In my opinion, more quality would be desirable to accommodate a plastic waste contrary to the motto "then I'll buy halt next year a new" I expected a longer life.
