I buy this as I work from home and sometimes long hour into the night . the room light can get pretty irritating on my eye for those hour and I be bill conscious . this light be great so far ! it feel and look sturdy yet flexible and grab without pinch - the usb do not drag down the port and sit pretty comfortable there . not only be the light bright enough to illuminate my full size laptop computer keyboard but give a area of illumination that cover my work phone on one side and my write implement on the next . Pretty strong light be what I be say !
