I purchased these for an indoor kennel set up.Cons - the fasteners between panels are sort of a pain to tighten. The wings are a hair too wide which makes it get caught as you??re tightening them. I used pliers to get them tight and secure, and in the process, scraped up the pieces. I also had a hard time perfecting the panels and getting them ??square??; however, I used two kennels and made them (1) 4x4 and (1) 4x6 - which in fairness isnt the original intention.Pros - for the money, I think they are sturdy enough and look very nice. These are exactly what I am looking for!I am overall very happy!
