The first disappointment is the assembly manual. One page is devoted to what the manufacturer is responsible for and what the manufacturer will not do. They are responsible for nothing. If you want a replacement part do not bother asking, you wont get it. You build it from the bottom up. Given the overall weight (about 145 lbs) of the cart this is a good thing. After getting the thing assembled there is no need to turn it upright, especially with wheels on the bottom. Or, when you are working alone. After the base is assembled there comes assembling the central part of the cart, the part that ultimately hold the drawers. The instructions are to assemble the parts without screwing anything together. This makes sense because some parts are held together primarily dowels which would be very difficult to fit together if some parts were screwed together first. When you begin to screw things to together everything falls apart there is not friction to hold it together. I finally solved this problem by using the top rails, which notch onto the lower structure. This stabilized the lower structure enough that it could be screwed together. In the last step the drawers were assembled and installed. The big one at the bottom fit pretty well. Two of the smaller drawers fit well, the third drawer easily fell of the rails. Testing proved that all three of the drawers fell of the one set of rails. I finally added a cardboard spacer, about 1/16 of an inch, on each side of the drawer. That drawer now operates well. Conclusion If you have the time and inclination to assemble a piece of furniture that has poor instructions, whose manufacturer denies any responsibility for anything, and may require special adjustments to work properly you may be happy. I am not happy as it cost me a lot more time than was needed. My time is precious.
