Our Classic MediCrystal® Amethyst Mats and Amethyst-Tourmaline ones with triangular windows design come with the 2-year warranty, the longest in this industry.

We cover all other new MediCrystal® and ThermoGem™ products with the 1-year warranty. 

Our factory-refurbished products come with 6-12 months warranties. Please check the listings for detailed information.

Whether the problem is with the mat or the controller, we will provide you with a free replacement as soon as possible, usually within several days after you contact us. 

Shipping and return shipping is free for warranty issues.

After the warranty expires, we take care of any repairs, at minimum cost. 

Our warranties are for home-use and do not cover professional or commercial use. Please contact us if you are going to buy our product for your spa or massage studio.

You can also buy a 5-year extended home use warranty.

It costs around 40% of the retail price for classic mats and 60% for the mats with additional functions like PEMF or Photons. Please, ask us if interested.

We additionally protect your investment with top-notch customer service, risk-free trial policy, and lifetime trade-in commitment.

So even if your product's warranty expired, or it is damaged, it still has significant value!


We have a trade-in policy for those customers who purchased a full-price brand-new product at our Far Infrared Amethyst Mat Stores on Amazon or eBay or directly from us. 

It works only for the purchase of a new mat of the same or higher price.

If the old mat is in good working condition, a customer can get a trade-in allowance equal to 40-50% of the amount paid for the original product decreased for sales taxes and our shipping costs, free products, rebates, and promotions provided at the moment of the original order.

We apply this policy to the non-functional, defective, or damaged products as well. So your product always holds value, no matter what condition it is.

"Shipping costs" are the expenses we pay to ship the original mat to the customer. Though we offer free shipping, these costs are in the listing prices, and we pay for the product delivery to you.

These shipping costs range between $20 and $150, depending on the product size and model. For example, we pay $20-25 for a mini mar, $30-35 for a midsize mat, $50-60 for a professional one delivery to the customer within the continental states.

If you received any special promotions, discounts, or rebates at the moment of the original purchase, or the order was previously refunded partially or in-full, the basis of what you paid goes down for the same amount.

The exact trade-in value depends on your mat age and condition.

This policy does not cover used, refurbished, or discounted product purchases, products in professional or commercial use, products purchased from other sellers, outlets, or private parties.
