With all items there is a link to the product on Amazon or the manufacturer’s own site. I can sell the item, but I can never beat Amazon for speed of delivery, options, and cost. So use the link and it will take you directly to the product. These are the exact same items I trust and use everyday in clinic with patients and personally use myself. I stand behind these products 100%. These links earn me a small commission as an affiliate, but in no way increases the price you pay. Please do not spend any money on these products unless you feel you need them or that they will help you.
