Bests & Worsts Reviews from Amazon

The description of this product on Amazon specifically describes it as providing "infrared therapy". In order to be considered infrared, the light source must have a wavelength above 700nm, which is above the red edge of the visible spectrum. In other words, humans can't "see" an infrared light source. Although near infrared and far infrared light sources are used therapeutically, one of the most common sources of IR energy that's FDA approved to treat pain is in the 800 to 1200nm wavelength range. This is not visible red light. The visible spectrum of red light spans from 620nm to 700nm. When the foot massager was delivered to me, I saw that the "infrared therapy" advertised on Amazon was actually nothing more than 4 little red lights. In fact, both the manual that came with the foot massager, and the box it was packaged in describe the light source as a "red light device" NOT an infrared light which was advertised on Amazon. I uploaded a picture of the box the massager came in, and as you can see the manufacturer describes it as a "red light device". Since the massager emits visible red light, then it can be considered "Red Light Therapy" which is basically based on the belief that the energy emitted by visible red light can penetrate human tissue and have therapeutic effects. As a licensed Physical Therapist I am not advocating on behalf of infrared therapy over "Red Light Therapy", my only issue here is how this foot massager is being falsely advertised on Amazon as something that provides "infrared therapy". There are many foot massagers on Amazon that are half the price of this one, and they all vibrate, generate bubbles and heat the water. What sets this one apart from most of those less expensive models is the claim that it provides infrared therapy by way of an infrared light source. What is being touted as "infrared therapy" is nothing more than 4 little red light bulbs embedded into the bottom of a foot massager.
