“I purchased one of these for my son and one for my daughter-in-law for Christmas, and my daughter (an RN who knew the science behind it without being told) wanted one as soon as she saw them so I gave her. They all love them and my son, who has some significant anxiety issues, says it's really helped him. I then had to buy another one for myself. Today, when I was really stressed out, my husband told me to go get my "breathing thing" because I was upset. He had originally scoffed when I purchased it wondering if I really needed it. After today, when it helped very quickly, I don't think he'll doubt it again. :-)”
