I needed a monitor arm that could articulate in as many ways as possible with multiple mounting options in order to fit it into a very tight space in a secretary desk. After trying three other options, I went with a desktop monitor stand from Displays2Go (LTGSPNG1A). It was a little more expensive than the others, but you are buying quality. The monitor moves easily and the tension on the arms can be adjusted in two different places in order to accommodate many weights. Also, the package arrived a few days late even though I ordered overnight shipping, but Displays2Go refunded me the difference between the overnight and the regular freight price. Good, honest business!
