The SunSniper nylon fiberglass bearings NFYI makes his long name! The part appears small and at first glance, not quite stable, while trying out but it turns out to be false! A real help, especially if you are traveling in nature, or sometimes with the girlfriend / wife wants to hold hands! The NFYI makes this possible! The camera remains at their given space and is very easy to re-attach there and also to solve! I regret the purchase in any way !!! ADDENDUM: In the meantime, I am no longer so enthusiastic about the Sun-Sniper AC! Because the Sun-Sniper holding the camera directly to the pants can come to the the paint is rubbed from the battery grip! That does not look so great and reduces the value of the battery grip !!! Therefore, I have two stars pulled off !!
