I initially ordered a single cabinet just to see how well the cabinets were built. I was surprised and the high quality of the cabinet construction, the operation of the drawers, and the accessories (the feet and rollers). I then ordered several more units.The cabinets come with very high-quality feet and wheels. In my case I needed to use the wheels as I wanted the cabinets to roll in and out under my work surface. That worked out well since I now had extra high-quality feet that I was able to use on a non-related product that came with pretty terrible feet. The quality of the wheels is good and should hold up for a long time.The cabinets came packaged extremely well. Heavy cardboard outer wrap, 1 inch foam all around inside with 1/8-inch plywood corner protectors and 1/8” plywood protecting the top. The top also has a removable protective film. I was concerned about disposing the packing material but I used Craigslist and gifted the foam to a fellow that wanted to insulate his garage doors. The cardboard went to a fellow that will feed it to worms in his mulching pile.Assembly was easy. Unpack, screw on the wheels and handles. That is it. A tool to tighten the wheels is provided but you will need to provide a 5mm hex wrench to attach the handles. Odd that a cheap one was not included.Unfortunately, one cabinet was not delivered. I contacted FedEx and they confirmed the number of items shipped by the vendor. I contacted the vendor and about 12 hours later I got a response, apologizing for the mix-up and said they would take steps to get the missing unit to me ASAP. Twelve hours later FedEx dropped off my missing unit. So, while messing up the original delivery was not so good – the customer service was fantastic.The cabinets all have different keys. I guess whether good or bad depends on the user. The cabinets are in my private home office so locking is not that important. I don’t know how hard it would be to re-key. The locks and the keys have a 3-digit number stamped on them so matching keys is easy.Bottom line I am very pleased with the cabinets and having all my storage match makes my home office look very professional -- and I did so on a good budget.
