Panel back is in 3 pieces which is not necessary, and if you move the adjustable shelf, the spacer connecting 2 of them would show. One of the back panels was not cut right (too wide) and we had to trim it to fit. Also, there were a few places where there were no pre-drilled holes (and back panel would not be secure without them so we had to make our own).  Once assembled it looks fine except I won’t want to adjust the shelf because of the divider that would show if I do.. Other than that the piece looks nice now that it’s together.
