The Matthews Vacuum suction cup lets you easily place cameras up to 2.3 kg on non-porous surfaces, like metal, processed wood (lacquered), ceramics and glass. This makes the Matthews suction cup a good match with GoPro, Sony RX0 or other light and compact cameras. These let you attach your GoPro to a surfboard or the Sony AX53 to your dashboard. The Matthews Vacuum suction cup comes with a ballhead with quick release that lets you lock your camera at all angles.
