Cheaply made, too large for dwarf hamsters.
I bought this for my dwarf hamster, but I won't be able to use it. The gaps between the platforms are too large for a dwarf hamster to cross. Also, the product is poor quality: blobs of glue all over the toy, splinters sticking out from the edges, one of the bells didn't even have a knocker on the inside! Overall, poorly made and not suitable for dwarf hamsters. However, this is a very cheap toy, so you get what you pay for I suppose.
