Question: When the ache/pain in my upper back won't stop, I always turn to this product. It takes away the pain almost immediately. It is adjustable and comfortable to wear. I love it!!

Answer: positive

Question: I can't let go of the design and the color of the metal. It looks very high-end! Hold it in the hand is even better! I can easily open a bottle of red wine right now, and I don't have to worry about pulling the plug.

Answer: positive

Question: OK. I was really skeptical about this one. Like REALLY skeptical - despite reading the studies out there about Ashwagandha actually working. But, I'm taking a few other supplements by this company, and they have all been good, so I figured I would give it a try. This is my favorite of all of the supplements! It really does help - it's like it loosens some of that tight pressure feeling I always carry around in my chest. My life has been very stressful, but this really does take the edge off of the overwhelm. Pleasantly surprised.

Answer:
positive
