I had the Discovery for a while and when I bought it they did not have the phone specific mount for my phone out yet (Galaxy S7 Edge). This caused me to buy the universal mount, which was absolutely horrible. I hated it so much I would up giving it away. The phone is affixed using these four knobs that move freely until tightened and I found it nearly impossible to line the phone up properly. It seems though it would be decent if you got the mount made for your phone, Im not sure though. I just bought the GoSky for 20 bucks and I like it a lot better.
