Corroded after a year

This mirror is very affordable and I liked the style, however the catch is that it is very poor quality. Had no problems with delivery or hanging, but after about a year of use in our bathroom, the reflective surfaces of the mirror are starting to corrode (or oxidize? not sure what the exact terminology is) at the bottom corners, making it look really bad. Skip this one and buy a better quality mirror, trust me on this one.

We love this mirror and we would give it a higher rating but we ordered two for our bathroom, and after hanging, noticed that the frames were slightly different. The product numbers and the sku's are are same but the width of the frame is different. We have ordered a third mirror and hope it will match one of the 2, and we will return the odd one. Otherwise I have rated it a 5.
