these work perfect for my son's toys. sometimes they get stuck because they don't weigh much, however they are well worth the money and I would defiantly purchase again. the colors are also wonderful and bright.

These are smaller then the original ball popper balls and they feel less durable but they work fine. I'm sure that if I lightly step on it the ball will flatten , and my baby has already made small indentions today from trying to chew them. However they work just fine. I see these working for MOST ball popper units because of the size and light weight for air powered machines. I'm happy to have 12 extra because they get lost continuously and we were down to 2-3 at any given time of the original balls and I have to hunt for them daily. My son loves the ball popper so it's pretty important to have extra balls. They work well.. They are intended as pet products, not as replacement balls but hey they work. The size/diameter of the balls are similar to the Hape pounding ball bench balls and they are too large for my 16 month old to fit into his mouth. I posted a picture side by side to show size comparison to the original Playskool busy bugs popper balls. Note: Some people said these don't work but they work fine, just as well as the original ones. My son has a habit of throwing small heavy wooden balls in there which jam, these are so light I don't see where anyone should have any problem with these working for any air powered ball popper machine.

I bought these because they were advertised alongside one of the ball popper toys. These balls are slightly smaller than the ones that go in the machine and fit perfectly in the babies mouth :( Needless to say, I can't use them in the ball popper.

I bought these to supplement the balls that came with the playskool grow n play busy ball popper (which my little ones love!) These balls are a little bit smaller than the originals, but work perfectly . Its fun to see them popping out like pop corn.

Even at $5 a bag, these don't seem like a great value. The balls are fairly small- ferrets are small too, I get it. But in order to half full a smaller container, you'll need to invest in more bags than you'd care to buy. I bought 3 and it was barely more than a single layer. Nothing that would satisfy a ferrets need to dig and bury. Double the quantity for the same price and it would be worth it.
