I delayed buying one of these because of the BS slanderous competitor's online reviews, etc. Pisses me off. This is well worth the money--super construction, super safe, super fun. (I did pay the $300 for installation because the review on this site said it could take 2 hours to 2 days, and I'm glad I paid for it.) But what I love most are (a) this is the first time my kids have voluntarily headed outdoors after school (no more immediate screen time) because they love being on it--if only to play pokemon or wrestle (which they do a lot, and it is cool because they don't break any furniture or themselves) and (b) all of the neighbor kids want to come over to our place. Lastly, the super strong zipper, once I added two keyring loops to it can be "locked" or using a rappelling (?) caribeener (?; like those in sunscreen bottles sometimes--the fake ones), I can keep young kids off or everyone off (reducing my liability and the risk of unwanted visitors. I really like this. Also, it sits on a slab (does not need even 3' of space from fence, and never moves. This is great!!! I know they will use it for years.
