The product design is great and really dressed up the room compared to a traditional crate. However, the track that the retracting door operates came broken and we have not been able to fully remedy it. So it does not operate as designed but it still kinda works with some effort to open and close the door. Would be much more happy with the purchase if the track had not arrived broken.

Ex Input:
These Twix bars are produced in the Netherlands; they do not taste the same as US-produced Twix, so if you are expecting the US version, you will be disappointed. The expiration date on the lot I purchased was 2 days after the shipment was delivered.

At first reading the reviews, I was thinking there was no way she did that. After reading, I still felt a little skip every time Tris came up. It makes sense. Obviously, I'm not happy about Four and Christina being together, but I'd rather it be her than someone who doesn't understand him or Tris. I kinda wish there was more about Caleb though. I'll take what I can get when it comes to the divergent series.
