Installation is easy (just measure carefully!) and feels very secure. There have been some reviewers who are concerned that the screws may come out of the wall with the weight of the mirror... I suspect they are not using the bolts properly. No surprise here - the instructions are too brief, and they don't describe this critical bit: the bolts are NOT typical drywall screws with plastic inserts. Those expand as the screw is inserted. Rather, this mirror ships with molly bolts, which have a piece which expands on the back side of the drywall (inside the wall). For this piece to expand, the bolts must be inserted fully and THEN turned many, many rotations (50? 100?) to compress and cinch the anchor. When this is done, they're very tight and quite secure.The mirrors also look very nice, and the tilt feature is perfect for our young kids. Very happy with this purchase.
