Cradle for a PC laptop charging block
Color: Black
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.

Don’t but this…
Color: Black, Color: Black
The holder came quickly and isn’t that bad but mounts with a huge adhesive backing, which again isn’t;t bad, but it was sent in a plastic bad, like a zip lock bag. The adhesive backing has NO protecvtyive strip on it, so it is covered in lint and debris and was sticking to the bag it was sent in.
