Works great for right space!

I got this to hang a sconce on the wall where a cast iron vent pipe was in exactly the wrong place. If you follow the instructions exactly, you'll have no problem getting this to fit through the 4 hole that you cut in the drywall; the two flat edges allow it to slip inside a 4 round hole, and with a little tilting and finagling, you will be able to get things rotated where you need them to be without having to cut any extra for the ears.One thing that could be a little better is having slightly longer screws for the outer ears. Once 5/8 drywall has texture on it, it can be a little thicker than 5/8, and then it's extremely tight with the short screws the box comes with. I was a little afraid of breaking the ears. But in the end, it worked out.It's also quite expensive for what it is; ordinary old-work round boxes typically cost just a buck or two at a home improvement store. Even as a specialty item, a price point closer to $5 would make more sense for this, but if you need one, you need one.
