I bought this with a small bracket that allowed me to attach it to the monitor. The mount will not work with monitors or screens thicker than 1/4 inch. I tried using a suction cup but the back of my monitor is rough and protruding so I used the gel sticker that came with the suction cup. The gel sticker didn't stick and the suction cup mount kept falling off. I had to resort to clear tape to stick the light to the back of my Samsung monitor. The actual light cube works great. Too bad they didn't make a mount that could span a little thicker than a quarter of an inch.
