Double the price of the large box (same brand) but they DO NOT tighten. I bought a couple of times hoping they would improve but NO. Wings are fragile. hard plastic. The metal screw heads are stripped before tightening. I even tried pre-installing them, but found that if you tightened about an inch, they just snap. If you have the space, spend a few bucks more and use a box designed for a ceiling fan.
