The intelligent surface of the nano-pads sucks with countless tiny suction cups on the surface of the Bumper, the iPhone or the iPad.
It can be easily solved and used again. Please note, however, that the pads also become slightly dirty if you often loosen and reconnect the gadgets, or if the case lasts longer without content. Then the suction decreases and the surface of the nano-button can be cleaned with a damp cloth (WITHOUT CLEANER). Then let the button dry and insert the iPhone / iPad again.
