I am very disappointed with my purchase.  I bought the 71x24in large mirror and it came with a light weight keyhole plate with the wrong size screw and anchor. This kind of heavy mirror need heavy duty anchor screw with a matching keyhole haning plates so that the screw can fix inside the hole and stay. The keyhole hanging plate is attached to the back of the mirror and it is the light weight one for the lighter haning frame, not for 71x24 mirror.
The screw does not even fix in those kinds of flimsy haning plates. No way that I take a chance to hang the heavy mirror with those. I had to buy the durable hanging plate with the anchor screw that matcha and can holds more than 70lb to be safe. I have to hire the handy man to install the new haning plate because I do not want the screw go through the mirror from the back. It is very frustrating after I pay high price and long time for shipping.
The mirror itself looks ok from the front but the frame, brackets and the hardware is not.
