The heater cover goes through many tests. Sometimes as a new product is developed tests are not seen until there is an issue. Then another check is added to the overall testing checklist.
If there is ever a bad product, swap it out and let them know this is one of the firsts, and that we are sorry for the bad experience.
NOTIFY customercare@elev8distribution.com immediately to let them know the situation. You may have been the one to find a new test we must implement.
