The first time I bought a cat playpen I had no problems. My most recent purchase of 2 more of the same( cat playpen / cage from this manufacturer): both seemed to be defects or seconds. There were clips missing- the clips that lock the doors & the main sides, front and top of the cages were bent and made it very difficult to assemble due to alignment issues and left me with two lopsided cages when I finally got them together. Was not too happy about that.
