I guess that I should not be surprised at the sub-par quality given the price, but I had hoped for a little bit more.  First, the shelves are not straight because the holes are not cut evenly on either side.  So that kind of ruins the shelving unit entirely in the first place.  That's not where the problems end, however.  In addition, the supports for the glass shelves are these really ugly metal tabs that you put suction cups in.  Which look terrible because you can see the suction cups through the glass shelves. Third, whoever "designed" this disaster of a shelving unit made no effort whatsoever to incorporate the screws into the design, so there are these awkward silver screw-heads sticking out all over the thing.  It's really really horrible and cheap looking.  Don't buy it.  There's no level of DIY that can fix this horrible thing.  Probably the worst thing I've ever bought from Wayfair.
