This mount, while rather big and cumbersome at first site is that way for a reason. The mount attaches around your rearview mirror and hangs down to hold your phone in a horizontal orientation. This provides a solid mount for your phone, one that is free from shifting or moving due to bumps. It is solid in construction and can fit a variety of phones with or without a case. I highly recommend this as it provides a much better and more solid mounting than suction cup and magnetic mounts that tend to fail in heat.
