Dear Rebecca
Thank you very much for sharing your detailed and thoughtful feedback. We sincerely appreciate your perspective, and we fully understand your concerns regarding the lack of English-language instructions and technical information.
First, we would like to offer our sincere apologies for the inconvenience this has caused. Clear safety guidelines, usage instructions, and product specifications are essential, especially for a product that involves heat and FIR (Far Infrared Ray) technology. Your expectations are completely reasonable.
To address your concerns immediately, we have provided the following materials below, and we have also uploaded all documents on our website for your convenience, so you may access them at any time:
Complete English Instruction Guide
(safety precautions, proper usage, expected benefits, cleaning instructions)
Technical Specifications for the FIR Mat
(wavelength range, heating levels, power output, material composition)
General FIR Information

We fully agree that without proper documentation, it is difficult to compare this product with clinical or research-grade FIR devices. Your feedback is extremely valuable, and we are already working to update our packaging and product materials to better meet customer expectations—especially for customers with medical or scientific backgrounds such as yourself.
We also appreciate your positive remarks about the product’s build quality and packaging. We hope the attached and online documentation will provide the clarity and confidence needed for safe and proper use.
