Works like a charm. I first connected the device to a spare 12V battery. Be sure to connect the red clip to the positive pole and the rear clip to the negative pole. The red light on the device will illuminate to indicate the connection is correct. Then connect the device to the OBD II connector. The device will start beeping to indicate that the connection is set up correctly. Change the car battery and then disconnect the device from the OBD II connector. I had no problems with this device.
