Just so you know, it IS genetic...

From my brother, Renaissance Man...
Just fixed one of the white drawers in the playroom with the new slider (from a year ago??).

Works great - especially when I don't:
1. put them on upside down
2. backwards
3. at different heights
4. missing all but one screw.

If you avoid these problems (or fix them) then everything works great.
