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.

Works great, super easy to install

Color: Black

Easy to mount, fits large charger great. Low profile appearance keeps it out of sight, functions perfect for my needs. The thick silicone material is nice and stretchy, thick so it should be durable.
