Step 4 indicates that 2 more of part 1 should be used than is true. Two of the holes are there to later receive part 3. Step 10 should be completely disassemble the unit because step 1 didn't show proper orientation. Step 13: Discover that there are 3 completely different things labeled part 9. Step 19 has clarifying text that might have been useful to have in step 10 (as written, not the take it apart and try again one).
Bad instructions aside, it's going together fine and is looking pretty good in its almost finished state. Looking forward to putting stuff on the shelves.
