    The product is good but the store only has limited amounts I needed a size 12 or 13. They only had size 11. I purchased it and have regretted it ever since. Also note there is a year or monthly fee. Yearly $69.00 which was not really realized at time of purchase. I have since cancelled this service. Use it as a pinky ring!

    I absolutely love this. I’ve had it a couple of months now. So not an instant review like most are. When I knew it really was what it said it was. Was when I got sick. Do you know it knew I was sick before I even had symptoms. I’ve purchased a lot of things in my life. However, I have to say this is in my top 5 best buys, no pun intended (I purchased it at Best Buy).
