He survived the first summer they would .If the ring jumping I think that it would not be as good.
The pool was easy to set up .The Filteralge ran with me via a timer and had to keep the pool clean no problems.
A sand filter at creating more people like 3-4 would be Board Ammer.

But you really need a flat surface otherwise it will be wrong.
Although this pool gets older helps then (as at a friend's) not a plane more then the worn out sometime and you do not get Ihne more degrees.
But for myself first 5 Star
