Its a very nice unit. However the bottom drawer won't close properly even after a few tries of checking assembly. & I believe that affect the locking mechanism?
 I would like to suggest adding a hole in the backside of the shelf where so that the hookup of the electrical can escape and your shelf doesn't have a huge cord going through it? the cord takes away from the aesthetic of the shelf and also gets in the way.  Please note that I like this product; but I feel there are a couple improvements that can be made :) Thank you!
