Difficult to line up screws onto tabletop because skipped from step 2 to step 6, then back to step 3. So had to undo step 6 and then go to step 3, 4, 5 - all went well. Keep screws loose until all in place, then tighten. Definitely takes two people. Flashlight useful to help line up screws with anchors on underside of desktop. One plastic screw anchor came out but not in a strategic place. Looks very attractive, and nice large size for two monitors. Sturdy.
