Easy installation even solo. Cheap zip ties, ok for install but get better ones later. Also the top has a flat square design ( just asking for water to collapse the structure). Easy fix, just  place a light weight 6 inch PVC pipe or anything else round across  the middle top to create V shape and raise tarp slightly to make rain run off.   My chicks are happy running around like little excited kids with all the room in  this 9x18 affordable pen.  I advise you to run 2 or even 3  foot high cheap hard wire mesh around the bottom of pen to keep pesky raccoons from reaching through this larger chicken wire  to grab your girls    I was satisfied with   this product for the price.
