Velcro holds better than others found in a box store.  Adhesive takes some effort to peel off plastic cafeteria tray.  Definitely not on a painted/poly/veneer surfaces-will lift off the finish.  I use these trays as a laptop tray.  Dell precision laptop holds.  I cut the tapes into about 1" squares.  I don't know about the longevity.  I would not trust this tape to hold fire extinguisher as in the photo.
