Very good product

Arrived on time. I found the product very useful and would recommend it, barring any contraindications, to anyone suffering from cervical pain and related complaints such as headaches and back pain. The patch retains body heat and its benefits are already felt a few hours after application. I recommend keeping it for a few days until the disorder has completely disappeared. As a user, I can only say that it works and that I have already bought more packs and recommended them to friends and family!
