My unit arrived well packed and with no damage. The instructions could have been a little better but if you take your time and think ahead it will go together with no problems. It took me about 3-1/2 hours. The slides on my unit work fine but if they tend to stick, some bees wax or a light cost of soap on the glides will will help them run very smoothly. Several reviewers complained of stripped screws. I suspect these were on the bottom of the CPU base from trying to force it in place. Attach the two curved brackets to the bottom of the base with the four screws, then back the screws off 1/1/2 turns so the slots in the bracket slide freely. Attach the two long screw through the main frame into the side of the base just far enough where they will hold. After the main desktop is in place, screw the headless pins into the bottom of the desktop. Then screw the long poles into the pins. Screw the long screws into the poles from the bottom side of the CPU base about half way. Tighten the long screws through the main frame, then the screws into the poles, and finally the four screws for the curved bracket. Someone complained of a flimsy drawer. Mine's is quite sturdy. I think the unit was an excellent buy for the price and it holds everything I need at the computer.
