This product would probably work decently well in a drywall application that didn't require any further wiring. Even so, I wouldn't bet on it working for a very long period of time. The plastic wings feel cheap and are tricky to get right, if you don't end up breaking them. I was trying to install one vertically (taller than wide, portrait orientation) but couldn't get the wings to rotate and lock into place like they're supposed to.
