Pieces do not stay put together 
The kit looks very cute, but it’s not stable when put together. The panels come loose when you press another piece to connect to them, and sometimes they just fall apart in the cage.
We eventually tossed it away.
I suppose you could glue the panels together permanently, but part of the fun is in changing them around.
Okay 
I enjoyed putting this item together, unlike the other reviewers my playground item was fairly easy to assemble and my hamsters still love it after several months. I especially enjoy the fact that the playground can be changed and shaped differently so it is a new item after every clean.
Playground review 
Yes, this playground comes in many pieces, but I think it was fun to put them all together! I felt like a kid again! At the moment, our hammy isn’t in the mood to try it out…she’s having babies. Hopefully, she and her little ones will be able to enjoy the new playground in a few weeks!
Great expansion for the cage
First off, ya gotta be a weakling or an imbecile to think this set is hard to put together. if you connect 2 pieces together at a time its as easy as can be. I built the entire thing in about 20 minutes, no problem. My hamster loves it as her new home (I think she likes the vaulted ceilings, lol.) Also, since I built my own cage by using a plastic bin container from wal-mart, this was an excellent way to be able to connect extra super pet pieces and be able to expand to the outside of the cage. By cutting holes in the bin top, i was able to get the tunnels to connect to this and bring them through the top. Overall, this an excellent accessory for any hamster.
Awesome!!
I love this product! It’s a challenge to put together but you can change it and make so many different structures out of it! I love the challenge! It’s like a puzzle and then my mice can have tons of fun with it too!! I’m buying another one!
