This original Samsung support is, however, a good compromise of stability and flexible usability, even for my (much smaller) Zweithandy Galaxy Ace usable. In addition, quality workmanship, ease of assembly and a useful sucker who does not constantly fall off - very satisfied!
Addendum October 2014:
The holder works for over 2 years without any problems yet, take it almost never from the disc. And also (my new) Galaxy S5 fits perfectly - with Silicone Case - really very flexible :-)
