Review on Versatile, Foldable and Transparent Hamster Playpen for Indoor/Outdoor Fun: Ideal for Syrian Hamsters, Rats, Chinchillas, Rabbits, Guinea Pigs, Gerbils, Hedgehogs, and Reptiles by Mindi Gefroh

Bought this to keep our two guinea pigs in while their cage was cleaned. That gave them enough space and also set limits. I also like how easy it is to store. It folds easily and takes up very little space when not in use. However, its use in guinea pigs had two disadvantages. First, the web pages are easy to chew and tear. Second, one of the guinea pigs escaped by standing on its side and pushing it down. Guinea pigs are okay, but you have to be careful as their size makes it easier to collapse and escape. This may work much better for other small pets.
