The pool is ok, but you have to remember that he is not as stable simple, like a round pool. The long edges go down relatively quickly and thus offer not so much stability vs. a round pool -. Especially when the pressure in the air chamber is not optimal. In addition, the pool can slow air - A day he keeps prop smoothly through, but if it is to have two or more days, then you have to re-inflate it in between..
While the pool reasonably well keeps the air, sees the roof is very different. This is quasi usable only for a few hours, then it breaks downright together before air deficiency. Too Bad. The roof by three chambers will be filled: in each case the two outer sides, and in the middle of the white brace.
