We bought the Banzai double sided slide, (the one with 2 slides side by side) about 5 years ago, and our kids used the heck out of it! We used it every summer, almost on a daily basis. We had up to 15 kids using it at once, and NEVER had any issues with the inflatable. It cost about 400.00 originally. The only issue we ever had was with the rubber hose, which was an easy fix. It was not wanting to stay together after 3 yrs in a spot where the tubes were supposed to connect. My hubby put one of those ties that tighten up really strong on it, and it lasted well after that. We had times when it got left outside to dry, and then it rained, so a couple weeks later we would blow it up again, and it would have a musty smell. I would scrub it down with bleach for our pool, and the thing would be sparkling clean again, smell gone. Just this year ours finally was damaged beyond fixing. :( It had been left outside again (originally to dry, but then it was rained on etc) so the hubby set it up on our trampoline so he could mow the lawn. Well, we forgot it was out there, and a month or 2 later we went out to get it and blow it up to clean it again, and a family of either squirrels or mice (we have a dried out retention pond behind our house so there is all kinds of wildlife), had been living under it and had chewed several holes all through the thing. There were way too many to try to patch. BUMMER! It was really our fault, but I guess we can't complan after over 5 years of tons of use. It was sooo worth it. I would buy a new one, but our kids are 8 and 10 now, (the youngest) and we usually rent the 20 to 22' tall ones when we have parties now anyway, so our teenagers and the adults can go on them too. (our old one had a weight limit of 250 lbs) To me, it was a wonderful investment, and I don't regret buying it. At the time our youngest were 2 and 4 yrs old, and couldn't swim, so even going into the pool everyday wasn't an option, but the water slide was! I would highly reccomend it! I got such great use out of ours! Good luck!
