Have sought to lift the unit off quickly, because it is used in a convertible for a Navi solution. As a base plate Brodit holder was mounted and glued on the Chrome ball. First, the bought "little" magnetic and not glued centrally, but slightly offset because the Navi is also used in parallel with the original clamp-holder in another car. The "small" magnet does not hold the Navi while driving and the device tilts downwards. Therefore bought also the "large" magnet for Tablet and tasted, ditto. Therefore useless in my eyes and in my case. Bought 1 ball and two magnetic holder for nothing ...: Conclusion Positives: adhesive bond holds bombproof and detach them again with the recommended tip. Flossing is less because fast breaks, rather maybe fishing line (this itself but not tested).
