Thermotex Gold Far Infrared Heating Pad review

Thermotex is a far infrared specialist, and the Gold is its entry pad for large muscle groups. It uses a single patented far infrared insert in a unit that does not bend or flex, aimed at the low back, hips, hamstrings, feet and sit bones. Thermotex says that after 20 minutes the wavelengths penetrate up to 2.36 inches to raise blood flow, and it backs the pad with a Pain Free in 30 Guarantee and a 1-year included warranty, with 2-year or 4-year extended plans for an extra fee. With the store set to US dollars, the Gold costs $169.00, more than four Pure Enrichment XL pads, and the brand's Platinum all-purpose pad starts at $259.00. The rigid build means it suits lying or sitting against it rather than wrapping a knee, and the description we could read does not publish temperatures or a timer. Buyers who already trust far infrared therapy may value the brand's focus; for most people, the $54.99 PureRelief Pro Far Infrared XL is the cheaper way to try it.
