[Q]: I have used this for my terrible joint pain from being on accutane. It has helped me so much! I have also used it on my husbands back for all the pain that he always has and he found relief from it too! So excited I found this.
[A]: positive


[Q]: Ordered size small in blue. I'm about 5'8, 150 lbs with more of an athletic build. This dress fits perfectly. The color is more vibrant than I thought it would be but I love it. Fabric is pretty good quality and there is a little stretch in it, but very comfortable. Very happy with this purchase.
[A]: positive


[Q]: They sent me a face mask instead of the chest mask, I haven’t returned it yet. this is the first time I’ve ever ordered from Amazon and gotten the wrong thing.
[A]:
negative
