I use this one but I Samshill...

I like that it works with my Note in a case even. It even fits a Nokia 1520. The one thing it doesn't fit is a USB 3.0 cable. Well not comfortably.

These look the same, but I bought mine from Samsung with my S4, I used it for my Nexus 6 and now I'm back on my S7Edge, makes it a little hard to hit the edge features, or even the keyboard close to the grip, but it works.

This is what I've been using for nearly a year. Works like a charm and haven't and any issues at all.
