It also fits small tablet devices.
This mount package includes Arkon"s Slim-Grip Ultra Universal Smartphone and Midsize Tablet Holder and a Bicycle / Motorcycle Quick-Release Zip-Tie Style Handlebar Mount with Elastic Secure Strap.
The Slim-Grip Ultra"s spring-loaded mechanism makes it easy to insert or remove the cell phone from the holder with one hand, yet holds the smartphone securely.
Included with the holder are 8 support legs (4 short and 4 longer versions).
The top and bottom adjustable-leg design of the Slim-Grip Ultra helps keep any side buttons and ports unobstructed.
