I practiced Yoga on my mat and it stopped to warm, please, advice how to reload the controller.
Sorry, but it looks like sensors or bimetal switches were damaged inside the mat, and it will need repairing. Amethyst mats are great for meditation or relaxation, but it is better to buy from us the same unpowered mat, which is much cheaper if you want to use it for active training.
Please, contact us for repair or replacement.
Please, remember the following precautions to keep your mat safe.
Never fold the mat while hot; never heat it in folded condition. Please, avoid walking, active training or applying pressure to the mat, or putting heavy objects on it to not damage the inner sensors and heating system.
When you fold the mat for storage, always fold it the same way as you received it, with the top surface with crystals on the inside.
If the mat is folded in the wrong direction, it may be damaged.
Though it looks hard and strong, like a stone layer on top, really, there are a lot of tiny parts inside demanding careful handling.
Also, the best way to use it is lying on a flat surface. Careful use is essential for durability.
