This product is the best purchase I've made to date for my children. It is a bit on the expensive side but then, the thing is gigantic. You really don't get a good measure of it's true size from the picture on this website. All right, down to business.
Strengths:
It is endless fun for the kids. The stitching is incredibly tough and has stood up to the endless pounding from the kids jumping, bouncing and sliding and even a birthday party. The waterslide is about 8 feet up and ends into the inflatable wall and not the pool itself. I was apprehensive at first but it makes for great fun as the kids don't half drown every time they go down. Have to be careful though, you can get some serious speed going down the slide. I'd stick the 'rules' that came with it... feet first. The pool is about 10-12 inches deep which also helps keep the excitement going. The climbing wall to the to of the slide is challenging as well for the kids. I read somewhere that the pool is for 4 years and up. The box says 5 +. My 4 year old has no problems with any of the features. My 18 month old really enjoys the pool and slide (But obviously needs CONSTANT attention and assistance)
The negatives.
This thing is a water hog. It continuously runs off your garden hose. I think we used about 850 gallons the first day (About 7 hours of continuous fun). This could get VERY expensive depending on your water billing.
It takes FOREVER to dry. The manual says drain the water and let run (inflated) for 2 hours. We've needed 3-5 hours depending on how saturated the nylon gets.
Did I mention this thing is HUGE? It weighs 128 pounds and has a huge (level) footprint. It's not something you can leave up all the time and not something you want to set up every day.
I know it seems to have some serious negative sides, but the smiles are worth all the money and effort.
