This pen is a blessing.  I recently broke my leg and have very limited mobility.   I also have a spunky 4 month old puppy that I can't take for her potty walks.
My sister gave me the idea of a pen that comes in sections to be assembled.  I looked at many different options and decided on this product.  
I ordered 3 sets and now she has a nice 20 x 25' pen to take care of her business and pull up some grass if she chooses. 
My hubby got the pen up in just a couple of hours. Now little Nina has a safe place to " go".
Nicely made, easy to assemble & it looks nice!
Thanks
