Those are the crappiest doors, or maybe it is just coincidence that every one I have ever had has been crappy.
If you want a square door I would suggest almost any other door out there over that one. I like Midway doors, stainless Williams' doors, and the old chinese square doors (used on Artic and other bootleg cabs, they are same size as midway, made better and had a nice juicy texture to them, and a huge coin return tray).
