Simply wipe the area of the laptop where you want to place the laptop stand. Let the area dry again. Then put the 3M double-sided adhesive on the laptop and press, leave it for a few minutes. Now you are ready. First you open the high support, so that it becomes a high angle. To use the lower angle, you retract the top bracket and leave the bottom bracket in place. The laptop stand will not leave marks or other residue on your device. It offers you easy and simple use. At the same time, it can bring you relief and comfort for your sore wrists, neck and back.
