The MediCrystal® Mat is a top quality, durable product with a long life and a very small percentage of factory defects. It is covered by a one year warranty, starting from the day it is purchased.

Your warranty is automatically activated if you purchased your MediCrystal product from MediCrystal LLC on MediCrystal.com web site or Amazon marketplace.

Our goal is to help you get the product working quickly and with no or minimal expenses to you. We will do our best, but, please note that though the warranty is full against manufacturing defects, it does not include typical wear and tear, accidents or improper use. Please, remember that the most frequent cause for controller failure is the power surge, which is not covered by the warranty. It is your responsibility to ensure the controller is properly plugged into a socket that is fully surge protected. If you believe this is the reason for your controller’s failure, the quickest path to resolution is to purchase a new controller from us which may cost $50-$100, shipping included.
