Pluses: The 2 set is really pretty and by far the instructions are GREAT!!! 
Minuses: The one top was painted on the wrong side so when they are next to one another, you can tell - this is annoying and I didn't noticed it until they we screwed to the the wall. One the other unit, 2 shelved came damaged so I had to use black paint to cover up the marks. This part doesn't really bother me, but the dull and shiny main shelf, is super annoying. 
I will stress, their instruction we spot on and the easier thigs I have evver out together!
