Beware, don't use if you have thyroid problems
I was looking forward to using the Red Light Therapy, what the Amazon listing is now calling Neck Warmer Device. When I received the device, on the outside of the package, in small print it states not to use if you have thyroid problems. I opened the package and the card attached said use with caution if you have thyroid problems. Which is it? Use or don't use? There was absolutely nothing on the Amazon description page saying thyroid problems would be an issue with red light therapy. Therefore, I have not used this item. Until I can find research or speak to a wholistic Dr that understands red light therapy I'm concerned if this device is safe to use in the neck/throat area. Not good advertising by USUIE.
