It was very overwhelming to put together and I found a lot of the pieces felt very cheaply made. It looks really nice but if you don’t have the time to spend to clean it out, don’t get it. It’s not very easy to clean. 
The platforms don’t stay in place at all and often pop out.
Wheels are way too small for our big boy but we did modify with a bigger wheel. 
He loves sleeping in the tube!
It gives the hamster a lot of room and he enjoys its but it wasn’t my most well thought out purchase. But all and all happy with it.
