This kit gave me the opportunity to better determine sizing since I’m between sizes and the rings do not come in 1/2 sizes. It was nice to be able to wear a “test ring” in two different sizes for a day or several days to determine which size was the better fit. FYI, they suggest going with the smaller size for best ring sensing. Glad I went with the smaller size. I’ve been wearing the ring (on my index finger) for about 7 days. I like the way it looks and it’s comfortable. It doesn’t interfere with holding a golf club. I’m still learning how to interpret the data and the capabilities of the ring but so far, it’s great.

Very true to size, Mimics the actual ring perfectly, wore for about 2 days to make sure I had my accurate ring size! Love this and the giftcard promotion as an incentive to go for the ring!
