Made in China - the biggest mistake. In addition, the pre-assembled fastening screws are set at an angle so that they cannot be screwed in when assembling the box. You have to loosen the screws and screw them back in by pressing on them to correct their angle. Once you've done that, hold the box securely in place and use a cordless screwdriver or Phillips drill to drive the screws in with authority and control over the box's position. Another problem is when the romex wire is pushed through the slots, it is difficult to pull them out in the opposite direction. When trying to pull the wire out of the recess, the wire insulation was damaged. I wouldn't suggest her. DM
