The name says it all... It holds tight and works with almost every smartphone having a 4. 5" to 6. 5" screen with or without a case. High quality, ultra-elastic silicone grippers tenaciously hold your phone for convenient display. The included strap mount rotates for portrait or landscape orientation. The Omni RideCase(R) is compatible with other RideCase(R) QuickClick(R) mounts, like the RideCase(R) CarMount or RideCase(R) Armband.
