I purchased two. Easy assembly and setup. I've been using them for a few months now and love them. Very strong and sturdy units. Able to customize the exact sit or sand heights then save to a button. I thought the videos were fantastic and helped a lot with assembly and usage. I highly recommend anyone purchasing these, WATCH THE VIDEOS! I Make sure you have assistance when handling the tops, they are heavy. I purchased a few accessories to manage my cabling and I'm very glad I did. They are not only very functional they help with aesthetics. If I have any complaints, the skid the desks arrived on are large and were difficult to dispose of. Twice when leaning over the desk to grab something I pressed against the control panel and the unit started to move.
