Use them as supports for my heat generating electronic products (router switch, android tv box and desktop projector ) that have bottom ventilation holes. The height is enough to ensure good airflow from below. Adhesion isn't the best, but if done right everything should be fine. Here's what I do when I'm dealing with something that sticks: Prepare the surface where you want it. hold tight. Wipe the surface clean with 90% alcohol or higher, removing any residue and oils that have accumulated over time. A good practice when moving speakers and electronics is not to pull them, but to lift them. Pulling is a major cause of bonded stud failure and delamination.
