Pros: Worked almost instantaneouly. Won't live without these patches. Size is great for my neck.
Cons: I feel that the smell would prevent me from wearing at work. Change smell please
Awlsome product. I will buy in bulk. I have been in severe pain in base of neck radiating across scapula area for over 6 months. I couldn't sit/sleep. Nothing worked other than being wrapped in ICE. I have almost no pain while using this product.The smell is strong and I don't think I can wear these to work. I bought these at our local Walgreens. Salonpas patch is going to my choice for pain relief. I will tell friends about this product. The size is great for the nape of my neck and they stayed on for over 8 hours. GREAT GREAT WONDER PATCH
