I was pleasantly surprised by how easy it was to open the box and take it out, put on my desk (which was less than 24"). VOILA - in 2 minutes I placed the screen, laptop and keyboard with no problem. Easy to move up and down. VERY STURDY and VERY WELL-MADE. I am glad I did not choose another brand -it sis worth every penny. The price is reasonable and this is just what I needed for the mandatory work at home during the Coronavirus period. It got here 3 days before the estimated delivery date. That was a big plus!!!
