The best way is not this way.

The best way to regard their pools is as "disposable". Mine came with a leak or two, if you just looked at it skew it started leaking air, but it was still a pretty decent little pool.

Fast forward 11 months...

Took the pool out of (carefully packed and protected) storage to set up up for its second summer. Ignoring the fact that it is a mold magnet (these things happen, such is life), it immediately started with the air leaks again - pretty severely.

Two days later and my finger physically went through the pool while patching the third hole (that I could find, there were others). I slid my finger sideways and the plastic tore like paper: it had become horribly brittle. I guess two months of sun last summer was too much for it.

Buy Bestway pools if you want something that looks good, but is sure to leak and won't last.
