I really like this mobile phone holder. EASY TO INSTALL - Turn the large knob to securely tighten the hook on the vent. Attach the magnetic strip to the back of your phone, put the case back on and yes, the magnet will work with the thick metal case. The magnet is so strong that I've been using it for a week and my phone never falls off and the mount stays in the same place. This phone holder is made of durable aluminum alloy, so it is very durable.
