I tried this on my Gerbil BB and he just would not even move in it. BB loves the excersize ball, but would not used this contraption. I think it was harder for him to make it move and a bit awkward for him. Save your money - just get the round ball instead.

Pros: Cute

Cons: Gerbil did not like

I saw this in my local pet shop the pther day while I was looking to get a few items for my hamster. I was looking to get this item ,but saw that it was a little pricey. At my local pet store it ran about $16.00.

Pros: cute

Cons: pricey

We had one of these for our gerbils when my kid was younger, she really liked to watch them run around on their "motorcycle". It was a little pricey, but added a little zip to playing with the gerbils.

Pros: great exercise, kids love to watch!

Cons: none found

my friend got one like this for her hamster, he would not go near it.

Pros: cute

Cons: pet will not use it
