Designing by the initial gravity principle of nature and eccentric circle conception.Can accommodate any size of marketed smartphone,more simple and neat.Outer rubber material,The phone heavier,the gravity larger.So the frictional force is relatively increased.When the friction is greater than the gravitational,the phone will be stationary on the plane and won't fall.

Use:Phone place below the products and homeopathic goes up.hen the phone contact with the product, the products will be rotated to circle center the center axis.And both sides will change width With the size of the phone.And then can let go
