Love these!  They are sturdy and flexible, easy to use, and quick to set up.  They don’t pinch fingers or scratch floors.  Ours has stood up to a lot of abuse from two kids, including the older kid climbing in and out and sitting on the edges — still good as the day we bought it.  They can be set up as a closed play area, or you can easily use a few pieces to contain a room or block off a hazard.  Just a great product.  5 stars.
