Using this tempered glass screen protector for your Omnipod DASH™ PDM is easy. First, clean your PDM's screen thoroughly to remove any dust or fingerprints. Then, carefully peel off the protective film on the back of the screen protector and align it with your PDM's display. Press it down gently to ensure it adheres well. As for maintenance, use a soft, lint - free cloth to clean the screen protector regularly. Avoid using sharp objects on it to prevent scratches. Also, remember that when you order case Peelz, it's just the vinyl Peelz for the case, not the case itself, and no devices come with Peelz products.
