Cheap, I m not expecting much. J have more protection from PVC and silicone has after a few months he is the only one I use for: 1. enhancement around the screen 2. perfectly operational buttons 3. Access to the microUSB port and headphone 4. thick enough to protect cameras (holes) 5. Protections of screen are acceptable (not great but offered so we will not quibble)
The small negative point: ca allourdi / thickened the phone and the black gel is that the black (contours), the rest is semi-rigid plastic.
Basically I highly recommend it, especially when I see scratches on the plastic
