We bought this slide several years ago for my daughter's 2nd birthday. The best thing about this slide is that she still thinks it's fun 3 years later! It is a taller slide, so although it's safe and fun for kids from age 2, it's still fun for older and taller kids. It's more expensive than shorter toddler slides, but the fun factor lasts a lot longer.
The slide is very sturdy. We never bolted in the triangular bases, but they do a great job stabilizing the slide. It's pretty easy to fold up, but it is still pretty bulky.
The only downside to this slide, if you want to look at it like that, is that it's fast. The first couple times new friends go down it, they always slide right off at the end and are surprised (and scared, if they're little). But this is the most popular toy at our house when friends come over. We often have to put it away when there isn't supervision, because kids will sneak to play with it.
