LOVE IT!!!  No assembly required.  It came ready to use. I was so excited to get it out of the box.  It's very sturdy.  In fact, I have it just sitting on my desk because I'm so tall that when I sit down my laptop on the desk was not ergonomically correct.  This helps immensely.  AND love the fact that I can stand when presenting or teaching on zoom.  The surface is large enough for two screens AND my keyboard.
