    This is the second time I purchased this ring. Love the way it tracks everything. I lost weight and my size 12 rose gold no longer fit so I purchased size 8 different budget so I went with this color. Not as feminine as I would want but still love it.

    Overall really good, tracks sleep, stress and overall health. Occasionally disconnects from my phone which is kind of frustrating. But other than that it’s a great product.
