Hello, I use these swivel end in the car combined with a universal holder of Herbert Richter for large smartphones. Although I have the part glued only with a strong double-sided tape, it reliably holds my Gelaxy S5. If you do not often move the phone keeps it forever. This I quite frequently but move it, I must now and then tighten the screw on the inside, otherwise loosen the joint. Nevertheless Price / Performance-wise, the good part, in my eyes!
