Review: Best toy!! - This may be the best toy I have ever bought. I have 4 kids ranging from 3 to 10 years old and they all love it. Parts are well made and worth the money. I bought the expansion kit and I’m glad I went ahead and made the purchase. Tube pieces are easy to connect but also stay in place. Each part is made durable and tubes are very thick plastic. I was pleasantly surprised at the quality compared to most newer toys.
Review: Makes the toy even bigger ! - Had the original air toobz since my sons bday had to buy the expansion, sometimes the balls get stuck but thats the only downside. Its a game multiple kids can play if you have enough balls. This expansion pack i was worried would be too long to work but it works great. The assembly is easy for an adult but my son doesnt built them sturdy enough so I have to help him or they will fall down. But its a unique beautiful sturdy toy. Teaches kids the power of the wind ! I love educational unique toys and this toy is visually beautiful. I hope they make many more expansive packs of even just the balls would be awesome.

### ⭐⭐⭐⭐⭐ Best toy at Christmas. Better than two Switch2 games!
*by E***H on January 11, 2026*

I was tempted to buy the cheaper version from China that Amazon sells, and I’m glad I didn’t because the quality is unreal., especially in the world we live in where we have to throw a toy out in a year or so because it inevitablybreaks. They have played with this nonstop. My kids are 7 and 11, and this occupies them both. I had to beg them to play one of the video games because I wanted to play it. The price tag is high, but it is worth it. Make sure you spend a little bit more and get the expansion pack, because it is needed for making bigger tracks.
