I ordered this pen for its good pricing.  The poles and how they interlock are good enough to keep my 50lbs lab in. It looks good and functions well.  Yes the steel wire ties were tough to twist around the poles to keep the fencing in place but this is needed to keep my lab contained. The only draw back to putting this pen together was the fencing and how it was rolled up and shipped.  The fencing was so badly mangled that I had to go to my local hardware store and purchase a roll of fencing myself which increased the price of this project.  I don't have the time to return the shipped fencing or wait for a new one to be shipped because I needed this pen immediately. I gave this pen 3 stars because it is doing what it should. The manufacturer needs better quality control while rolling up it's fencing prior to shipping.  Overall, it's what I expected
