I had one of these for my miniature hamster and she loved it! She used to roll around and explore the house all the time in this ball and we would always put her in it while we cleaned out her cage. It was a great place to put her where we knew she would be safe and where she had a lot of fun! We tried her on the regular size hamster ball at first but it was just too big for her but this mini one was just her size!

Pros: my hamster loved to roll around in this!

Cons: none

Hamster's greatest journeys were made driving her ball around my place. She was very enthusiastic and got in the most narrow places.

Pros: Very easy to use

Cons: Clear plastic loses clarity over time

We had one when our guinea pig was small. He liked it and it worked well, but he would urinate and it would get on the floor. He out grew it also.

Pros: exercise, fun, opens easy

Cons: urine ecapes to floor,

i think everybody that had or has had a hamptser has one of these. great to let them get exercise other than just in the cage/on the wheel.

Pros: works great

Cons: none

I have several of these and use them as a "holding" pen for the mice, rats, ferrets, and chinchillas while I clean their cages. It works great to give them a little time to explore, while keeping them safe.

Two complaints for this product. First, keep it away from stairs! As any round object, it can and will bounce down a flight of stairs, and this could seriously hurt or even kill the pet inside. If you have a cat or dog that may find it fun to bat the ball, be all the more careful. I have a baby-gate at the top of my stairs to prevent this from ever happening.

Secondly, be advised that the air slots in the ball also work as holes to litter urine and feces out of the ball if your pet has an accident in there. Be sure to clean your house very well wherever your pet may have wandered in the ball!

Pros: safe, easy to clean

Cons: air holes also leak urine and feces as your pet plays
