I bought the slide to go with this extension and thought I might as well go for this as I was spending enough on the slide. Im really glad I did buy it, it certainly adds to the thrill of this slide!! And the kids don't get sore bottoms coming off the slide because it is soft and continuous. In terms of quality, I was surprised to be honest by the quality of the slide itself as it seems quite bendy but I guess it's for children who are not as heavy as adults (not that I would have a go mind!) the extension is of the same quality but I don't see any reason why it shouldn't last. It only lays on the ground the whole time... Overall I am happy with the product, I don't think it is worth as much as I paid for it but the kids needed a bigger slide and are thrilled by this one. I bought it in April and it's been non stop play since!!!!
