Exercise Pens

I was wondering what anyone's experiences were with exercise pens for their hedgehogs. I am currently creating a makeshift play area for my hedgies, so that it makes it easier for me to sit and interact with my antisocial hedgie, Gryff and my sweet girl, Hufflepuff. I was planning on purchasing an exercise pen for safety and simplicity, because the makeshift play pen takes a bit of setup and a whole lot of cleanup due to the blankets. I was wondering what type of exercise pens were the easiest to use, maintain, store, and were enjoyed the most by the hedgies. Thanks!

I'd get the Midwest exercise pen. It is 15" high so is escape proof.

I use a similar one that is 12'' high from petsmart and I love it. I bought 4 and connected them all together so that he has a huge space to run and it folds up so easily.
