I used this velcro on my new pedalboard. I thoroughly cleaned it with alcohol before to ensure that the velcro would stick...which it did not.
The adhesive was very weak, often pulling off my pedals and the board.
It even seemed to not stick at all, some of the corners came loose even before attaching the pedals.
I ended up having to glue the velcro to the board and too the pedals.
Even after glueing the actual velcro grip is weak. I have ordered a different kind of velcro from Thomann and we will see. This velcro experiment is going in the bin...its a pity that I bought 5m of it.
Pros: Cheap
Cons: Cheap, poor quality
Spend the money and get better quality.
