Oh no, let's see if we can get it started again!
If your nail buffer is blinking red and turning off (after replacing batteries), check that there is no blockage on the top of the buffer. The top of the device (where the heads are assembled) must be clean and free of debris. Additionally, the device will blink red and turn off if the heads are stopped from rotating during use (too much pressure). To re-enable the motor, press any button when the red light flashes. If you still need help please reach out to us here.
