MidWest Foldable Metal Dog Exercise Pen

I have a TON of these and love Midwest pens. I breed Border Collies and use all sizes. They wear well outside and will eventually rust OUTDOORS, but they are durable and so very useful. The entry with the wire at the bottom is a bit of a pain at times, but they are sturdy in that area because of the design. When used inside the home they will last for a very long time if cared for by not bending the entrance or other wire elements. Eventually the clips used to hold them together at the ends can fail with heavy use (the little spring inside the clip wears down), but they can be easily replaced with other options or similar clips from the hardware store. When these X Pens from Midwest are not available, which is the case at times, I default to the Amazon brand which is comparable with some small differences in the gate entry and the connection clips. Mine have all been delivered on time, each in a good sturdy package that protects the contents and the pen is of good quality and durable. Very easy to set up and take down.
