The Luma is very easy to use! Your veterinary care provider will help you get set up with the device. You then download an app to your phone which walks you through your treatment plan. As your Veterinarian oversees your case your app will be updated with the latest protocols. If you ever have a question please contact your veterinarian. MedcoVet wants you to be comfortable with your device and treatment. Please feel free to share feedback with us anytime.
