The crystal butt water bottle certainly improved my water intake, I used to drink too little; I just love looking at the crystals. By the way, is it okay to put hot water into the bottle or would that upset the bottom part? Some of the bracelets are a bit short around the ankle (as suggested to do wrists and ankles). Because of gluten-sensitivity, I'm using the Allergy bracelet; no bad reaction so far, but maybe that's because I'm careful of what I eat?! Still testing the other products.
