I bought the exercise pen to use as an area to keep my small dog more confined to an area when its sleepy time and not allow him to roam the house and do his duty where ever he wished.  I was even more surprised to see that when placed into the pen he figured out this was his area and that stopped the potty problem. Go figure!

The pen is so EZ to setup and the door makes it super EZ for the little guy to get in and out.  I can't find anything that's bad and worth saying.  Heck, the price was even great

I give it an A+!.
