My son absolutely loves this.  I bought it for him for his second birthday to teach him about small and big and he got the concept of big and small very quick.  He loves running around the house with it expanding it and saying "big", and then collapsing it and saying "small".  We play a lot of games with it and I am quite frankly surprised that we haven't broken it yet!  Yes, my 2 year old has had it for almost 6 months and uses it daily and hasn't broken it yet!  I am impressed.  It's a great learning toy that is also great for games and physical activity.  I would suggest this toy to other parents of small children.  My son loves it and I am very happy with this purchase.
