I have a table with 3 monitors that took up too much space until I installed a monitor arm for each monitor. These hands are very strong. Only 1 out of 3 won't hold tight and I have to tighten the bolts about every week. I am currently using a 19" monitor, will buy a larger monitor and have my fingers crossed that they can handle it. The only thing I have is that the hand doesn't go far enough for me, but overall it's a good product .
