I have had this cage, the Habitrail OVO Studio, for a couple months now and I definitely have some pros and cons. I'll start with pros:
This cage is quite large (For a dwarf hamster)
This cage isn't very noisy (the sound is pretty much just a low rumble)
The cage is quite cute
Cons:
This cage is very time consuming to clean
The cage has bad ventilation, (I'd recommend connecting this cage with another wired cage by snipping the wires and putting in the tube)
This cage doesn't show your hamster, as well as a wired cage does.
In the main part of the cage, my Angel (my winter white) can easily climb out and run around on my counter. The base isn't very tall.
I wasn't able to put the tubes upright as Angel was unable to climb up them, she was too small.
I honestly would only recommend this cage if you were connecting it with a cage with good ventilation and this not being your only cage as it would be too small. Also, I wouldn't recommend this to anyone who doesn't like cleaning their cage for hours and doesn't clean their cage often.
