[Q]: 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!!
[A]: positive


[Q]: Only looks good in the picture, and the materials are very rough, stained and cheap. The copper is a lining not pure. I should’ve know due to low price but even at the price it is definitely very poor workmanship and not worthwhile. Now I have spend more money getting something better so as they say; better to spend wisely then hunt for bargains.
[A]: negative


[Q]: I couldn't put this book down. The author’s vulnerability and storytelling skills make every chapter compelling. It's deep without being heavy. I'd love to see it read in Bible studies Across the country, as it covers so many topics women silently struggle with: abuse, trauma, fitting in, perfectionism, marriage, aging parents, death, and so much more. Please read this book, and then pass it on to other women in your life.
[A]:
positive
