Seems to be pretty durable. I haven't had it long. The adhesive is still holding up as I applied it to the wall for a vertical hang to keep the block off the floor in my studio. I don't recommend trying to apply this to a wall that would have some kind of texture as the adhesive probably wouldn't hold very well. It's made for flat surfaces only or a wood surface. Make sure you clean the dust off the area you plan to attach to. As everyone knows charging blocks for PCs are incredibly huge and heavy; so far so good.
