I've definitely been happy with this treehouse slide for my 18mos old.  She really enjoys climbing up, sliding down, and she gets a good giggle out of the periscope.  The bottom of the slide has a fair drop to the floor, but if you've got this on a soft surface, it's fine.  My family and I put together this and another Step2 product on Christmas Eve night and were very frustrated with the directions, however, this product was simple enough to put together.  Good buy, overall!
