Here is my story and the absolute truth. I read about a different bracelet to lose weight. I laugh and so sad people take advantage of desperation. So I can to Amazon to see if they had another claim of "miracle" lose weight bracelets and they do. Around the same costly price. I am far from desperate could stand to lose a couple of pounds and definitely inches. I ran across these. WOW I thought but they were nice looking and bought them for that. Put them on thinking nothing about it. I went to the bathroom tinkle all night long. I do retain water. Thought nothing about it using the bathroom often and second night all night long like 5 to 6 times I'm not sleeping now. After three days I was telling my family I think these bracelets are doing something so everyone now thinks I a little nuts. Yeah bracelets I sound crazy and it happen again so the next night I took them off and it did not happen put it back on and the next night just like a faithful water pill. Now I know it's the bracelet. Go to my mom's house and she has one hand that stays cold. Pour circulation. I told her about the bracelets she put 4 of them on, kid you not 20 minutes later her hand is normal temperature. We both screamed. She has to wear a glove on one hand and has had the cold hand for years poor circulation. I am such a believer in this oh my gosh. My daughter suffers from migraines but won't take meds I gave her these. Now I'm completely out and ordering more. They are beautiful, work, and are affordable. I'm buying two more packs. They are fitting, like close to the skin. Wow I am blown away.
