It works great even for my large monitor! I can stand up for as long as I want and when I get tired I just hold the lever to the right and slowly lower or raise it to 2 different levels.
My biggest concern in ordering this was that it would be flimsy but I find it to be very stable. There is plenty of room on the surface for my laptop (and lamp mouse pad and coffee) but should be big enough and sturdy enough for a keypad and monitor. Very easy to set up and close up.
It changes levels very easily. Like that I can adjust level with one hand. Very sturdy support. Perfect size if you want low profile (which is what I was going for). You may be able to fit an extra monitor but I use it just for the laptop and mouse. Only thing that could be better is to get rid of the handle. The handle protrudes on the surface. The laptop won’t stay flat if you place it on top of that handle. But I’m okay with using it in the direction where you don’t place the laptop on top of the handle. And I’m sure the handle can be broken off.
