Query: Great for my Robo Dwarf Hamster

I bought this for my robo dwarf hamster. It took about a day for her to explore it. I put a little bit of bedding in the outhouse and she uses it as her bed. I like the wheel because it is outside of the cage, but I also still left the old wheel inside her cage. She uses both wheels to pee in, so I am going to buy a seperate outhouse with the litter in it and see if she will switch. (LOVE THAT YOU CAN KEEP ADDING TO IT) The pieces went well together, but the way I set it up it was a little wobbly so I just placed a folded up pillow case to hold it in place. The wheel did not have that problem, it hooked on fine and did not have to use anything to hold it up. The part that was wobbly was only wobbly because of the way I hooked it up on top, so it was top heavy. all in all it is a nice product and the wheel is bigger than I had expected.
