It is a very nice piece of furniture.  Files fit along side bars perfectly and move smooth.  The wood grain is great and wheels move easily.  
Setup:  I followed directions and was able to set up ok.  Pictures of screws and other parts were good and made it work.  I don't use lock so can't say anything about that.  Draws open and close with ease.  This is for home use and I am happy to say I now have my files organized thanks to this file cabinet.  Yahoo..and Thanks.
