Don't buy it if you don't have a sturdy, solid wood/ metal table. When you finally set up the arms, it's already a bit heavy, when you put on 3 monitors (for my case is 2x 27-inch + 1x 24-inch monitors) wow, don't test with your IKEA cheap table, my arms fall off because the table cannot hold all the weight, and it was broke. So I had to change my desk to a more solid wood (something like the office table) table, so far so good.
