Overall, they offer a great aesthetic look for those 'dead' corners and provide many decoration options for any room. I've purchase 3 sets of these and the quality is consistently very good, although I've seen misleading comments that they are not perfectly square; they're square, your walls are NOT. What I've done successfully, is to buy triangular shelf brackets that provide the right amount of shim (typically 3mm thick brackets accomplish that) AND the extra weight support for any heavy vases or metal sculptures. Yeah, its extra money spent but it offers the extra peace of mind that something isn't going to crash over time.
