The directions for assembly are absolutely horrible. Hard to decipher, too many steps per page, and they don't tell you how to separate the track pieces until the very end, and you really need to know that on page 2.(So look out for that)  My box arrived damaged and the direct parts replacement through the company takes 6-8 weeks, but luckily wayfair was able to replace my unit. Drawers slide ok, but the tracks seem to kind of drag on the side walls of the drawer sometimes. Still does the job, looks nice. The anti- tip feature (you can only open one drawer at a time) is definitely a plus.
