The Quick Mount for the S5 is great. It is very suitable for mounting on the handlebars, everything is tight and the short holder are undesirable vibrations do not realize (at V2 and 4 cylinders). A change of protective cover on motorcycle tours (Cafe, visit, evening beer garden visit) is nich required, it is not bulky and absolutely Mimics a silicone cover, but is a little harder. The screen protection cover I do not use, because the S5 is always protected even before water but raised the unit läst definitely fully operate.
Addendum: After frequent use, the bracket and the cover is tight still and still. The screen protection cover has been found to be awesome, it is mounted, you can operate the display of the S5 with the motorcycle gloves. For those who upgraded their S5 with a Samsung charger cover / battery cover for the inductive (wireless) charging, both protective cover and screen protection cover also fit for this. Inserting something goes strämmer of equip, then seated but like a glove.
