We are considering purchasing a Sand N Sun 16' pool mainly for our kids. I was wondering if anyone has owned one for over a year and if you would recommend it. Its one that the sides rise as you fill it so I was wondering, can you lean on the side of the pool or will water spill out if you do??? Are they durable? Are they worth $200 of my hard earned money??? I really can't afford anymore than that. Thanks for your opinion!
