CAS tester function: Is the CAS program running normally? Is the CAS data valid? Does the key have an inductive signal output? Is the key legal and valid?
I have it. It's occasionally useful but not what I'd call essential.

I have it. It's a great add-on for your bench testing the keys and to check if the eeprom was successful write and readable before installing back on the vehicle.
