Giving it a three star because I don't know whether I got a bad one, but one of the arms holds up my monitor just fine but when I put my other monitor, the same one as the first, on the other side, it can't hold the weight. Again, I don't know if I got a faulty one, but I can only use one side and my other monitor is just sitting on my desk with the stand, completely defeating the purpose of why I bought the mount it.
