We bought this pool last year in July and left it up all Winter long. It's all dirty inside now but it looks good and we can still swim in it if we cleaned it out and refilled it. My family had so much fun in it last year and I'm sure we will have more fun for the years to come. I can't wait! I love Summer and this pool is perfect even though it is a expensive to keep up with. The only part I hate is the those things that stick out inside the pool for the filter. I myself and the kids have gotten a scratch on our backs because of those things when we're doing the whirlpool thing. Also it could become dangerous when you do the tsunami wave thing with the tubes because the pool sides could burst so try to avoid that. This is a great pool for kids, teens and adults!!
