Q: The product is excellent, it was the only thing that finally helped me in pain. I'm glad I found it before the final possibility of surgery. Remains cold for a long time and much more reliable and has a higher quality than any similar product I have tried in the past. Also the service was excellent and it came on time.
A:
positive
