I think this product is really sturdy and is very cute. However we have to keep a cloth under the water bottle or else it drips so much we have to change the litter in the next chamber daily. We have roborovski dwarf hamsters and they are not able to climb the tubes so we have to leave our tubes down on the ground for them to run through so they don't fall.
The biggest one runs so fast on the wheel that he knocks it off several times each night.
Overall, I do like it. We have never had hamsters before and are having a good time with them.

Pros: Fun and cute.

Cons: water bottle drips, wheel sometimes falls off

this gives your pet great ways to work out and not just sleep all day. if your pet is shy or takes forever to get out of it's cage well not anymore this has easy axcess! to tour pet but be careful it can easly slip out so keep away from younger family members!!!!!! :0
