We replaced a slide that had been around for probably 15 years with this new one and were quite disappointed with the quality.  It seems pretty flimsy, and I will be surprised if it lasts more than a couple of years.  My daughter weighs less than 40 lbs., so I think it'll stand up to that weight, but I'm leery about going down it as an adult.  If I could do it again, I would pay more for a sturdier slide.
