A cell phone that only serves to call and worldwide because for a very modest price it is quad. He still owns the radio (I have not even tried!) And a small flashlight. This small lamp I find it really great and I must not be alone in thinking that because smartphones now trying to do the same by illuminating their screen. Practical menus, intuitive and simple as 3310! It is lightweight, all plastic and does not interfere in the pocket. For reliability, the purchase is too recent to have an idea but at that price it's not a very big risk taking.
