  • Fun and creative toy for all ages!
This was a such a fun toy my kids received. It was easy for them to use, great quality, light weight, and well worth the money. It has provided them hours of fun and will last them years!

  • Worth it!!
This expansion pack made all the difference! If you’ve had the main Air Toobz set for a while and have been wondering whether the expansion is worth it, the answer is yes. Having additional pieces gives kids so much more to work with, and we’ve gotten significantly more use and creativity out of the toy since adding this pack. It enhances play, extends problem-solving opportunities, and keeps the excitement going. Highly recommend for anyone looking to get even more value out of their original set. ... show more

  • Worth the Price
if you have kids it is an absolute must. It can be expensive but the quality is top notch. My kids have not been gentle with these over the past year and no so much of a crack has even surfaced. My kids were 3 and 6 the first year and they were easily able to put it together and play

  • Fun for all!
Overall we love this, the tubes just fall over more easily than I was expecting. But still fun!

  • Highly recommend the extra tubes/balls!
I really recommend buying the extra parts if you can. The extra tubes allow you to make more complex systems and the machine doesn’t have any issues with the extra tubes. It also has extra balls that allow you to do fun things like creating a ball shower and it’s nice not having to go search for more balls as often. Great toy, great accessories! ... show more

  • Awesome, but definitely pick up the expansion kit.
My son and daughter love this. My son has ADHD and has a hard time concentrating while playing on a singular thing. But the first day I gave this to my kids he spent 5 hours playing with it. It is also a huge hit for the rest of the family to build different shapes and such. I would recommend that you purchase the expansion for tubes as we have purchased 2 expansions and it just now seems like we have enough pipes and elbows to do really cool stuff. The product is well made and simple to use. Great fun! ... show more
