Whoever really has a problem with their back knows very well that it is "a comfort to the sick!" You simply have the feeling that it keeps your back stable! Great CAUTION because it burns and should not come into direct contact with the skin! Only over clothing! I got a burn because I put it on directly without even a tank top underneath!

I bought this specific belt, like any other belt of this brand, 10 months ago, having a problem with a herniated disc. I used it for the first few days and it did the job, but after 3 washes, the burning sensation it caused disappeared. Examining it by putting it on my tongue before the first wash, I realized that it contains capsaicin, which is found in the black marks on the red field. And I ask myself as a consumer, why do you, gentlemen of Firtech, deceive people? Why do you say that it contains biomagnets that cause hyperemia, while the burning sensation felt by the user is solely caused by the capsaicin it contains? As a consumer, I felt obliged to inform the world. It doesn't perform miracles, kids, just so you know, its effect disappears when you wash it. Now, if you want to throw away 50 euros for a belt that lasts at most six months, it's up to you. A cheaper adhesive patch does a better job.

It helped me a lot in avoiding back pain.
The temperature is not excessive, but I didn't have sharp pain to have a complete opinion.
