myself & my husband are both disabled & have trouble with our bones with arthritis . We love our Tronz:Z Lite & Tronz :. They help us by soothing the aches & pains that come with this condition. Most of my family have some kind of Tronz, not only do they help but also look really good. I love the Tronz necklace pink it's great, even my doctor commented on the necklace, it's great with the ions & magnets. Tronz is great.
