I was using this laptop stand at my workplace. I'm selling it because I've changed computers. It was used for three years, and the sponge has deformed due to the weight of the laptop. This is a used item, so please refrain from purchasing if you are concerned about its condition. The PS-002 with clamps LAPTOP STAND is a convenient laptop stand for setting up laptops, CDJ players, samplers, etc. Includes clamp attachment. In addition to being placed on a table, it can be clamped to a DJ table, etc., using the attachment.
