My drawers don’t work right because of all the above mentioned about the rails

Everything is finne except top drawer does not align correctly.

The 3rd wheel on the file drawer is a good design as it stabilizes the drawer and is nice support for ease of opening

Fit and finish of drawers is OK, the top drawer does not fit/align perfectly.

However, the two drawers are very useful.

poor quality - instructions are not the clearest especially as it relates to the placement/installation of inside runners for the top draw (instruction # 2 & 7 are poor illustrations) actually had reinstall these runners after all was assembled to allow everything to close properly
