eTopxizuh headphones and it pulled the black part on the ear piece rubber from where it was attached completely clean off with 0 residue showing the stuffing inside where the Velcro piece was sitting on top

The Velcro is still holding in in please with 0 movement and no leaning downward dipping compared to what the polar air cooler came with that was a single red sticking strip with 5 or 6 inlets with a silver bar that rests in between it to make it tighter or looser which if you move your laptop around the house and wanna carry it in your arms sometimes to take it downstairs or whatnot then after about a week or so the suction cup will come loose and you will have to constantly move it back into place which was a pain

I highly recommend this brand

Then they must be cleaned with Gu-Gone or some other similar clean

Do not allow to sit in the box twisted because it permanently distorts

I am amazed of this product's durability and strength
