Audio quality appears unimpeded which is awesome. The size and form factor is also excellent. Unfortunately the stickiness is inferior to other products. I have white duck tape which is sticking to the wall just fine. But this is already peeling up in numerous places.

Also attaching connectors to the ends is very frustrating (Or else I would just try to reapply a new stretch.

I may just rip it all out and go with small white speaker wire held down with white duck tape as that is easier to work with and actually stays stuck to the wall.
