Aluminum height-adjustable laptop stand with a ventilated design to dissipate heat. - Material: Aluminum - Adjustability: Height adjustable - Design: Ventilated design for heat dissipation - Compatibility: Suitable for laptops and tablets - Color: Silver Thank you for viewing. This is a laptop stand. I am selling it because I haven't used it much. It's not convenient for carrying around because it doesn't fold up compactly, but the material is sturdy and the neck is firm, so it has excellent stability. If you plan to leave it at home or in the office, there shouldn't be any problems. Please understand that it is not new. The fourth photo is just an image showing a computer on the stand, so only the stand is for sale.
