Cheap yet likely enough for whole pedal board and then some.
Personally, I needed this for just one pedal, and with bit unorthodox approach. I wanted to have my cab sim pedal at my fingertips all the time, but not taking space on my desk, so it's now upright on my rack's side, from where I can easily see it and change settings. It stays in place just fine.
Glue seems to be strong, but since I've had my pedal on it only for a week thus far, I can't comment on longetivity. But if it starts coming off, I still have 2,90m of it to replace the old :D
Update: after a month the pedal fell off due to the surface area the glue is in contact with being mostly soft padding. I think it would hold better with hard flat surface.
