I was extremely pleased with the price I paid, the shipping time, the quality of the items, and the overall ease of installation. I installed most of my cabinets directly to the wall studs about five inches off the ground, using mounting slots already in each cabinet, making it easy to sweep underneath or run power cords through the rubber grommet bottom holes. I also installed two base cabinets using standard castors i purchased elsewhere (mounting holes were already there and seem to be a standard as I found numerous castor brands all having the same hole spacing). Everything was very flexible in layout and installation arrangement, and with the exception of the optional castors, all mounting hardware was included. I was able to mount the top directly to the drawer stacks to make a relocatable workbench.
