RingConn Sizing Kit Smart Ring Gen 1 - Sizing Kit Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Find The Perfect Ring Size Smart Ring Sizer

used this to ge the size for gen 2 and worked perfectly

Cheap and accurate and free delivery. What more to ask.

I had used the ring sizers that they have to use before buying one of these rings at Best Buy. While the sizers there seem to be identical, putting one of those on for a few minutes, at the odd angles required there in the store is not a good indicator of what it would be like to wear on a daily basis. Wearing one of these sizers for a little more than 24 hours was a perfect way to not only choose the size but also got a good feel for wearing the ring with the sensor protrusions. I would definitely recommend getting these sizers and doing the 24 hour test run.

This product does what its intended to do -- my only reasoning for a 4-star review vs. a 5-star, is that i actually had to purchase this product prior to purchasing my ringconn -- its now a free option (and once you size, you really don't need this item any longer!)

This kit made it easy to find the perfect fit

This was a super idea to use before ordering your smart ring! I wore a size 11 for several hours, but decided maybe it was just a little too big, so I changed to the size 10 and wore that for several hours. I was happy with the size 10, so ordered that size in the Ring Conn...it fit perfectly. So glad I used this sizing kit first to save me frustration of returning and reordering correct size.

As much as I WANTED TO BUY THE RINGCOM, if I had, it would have been a mistake because I would not have been able to wear it! Having the pre-purchase wearing experience, I was able to determine that the ring is not for me. That said: PLEASE KNOW THAT I THOROUGHLY ENDORSE OTHER PEOPLE BUYING THE RING! It's a wonderful new concept! Thank you for the pre-purchase opportunity to try-before-you-buy!

I used this sizer to determine my size and then purchased the Gen 2. When the ring came it was too large. I think the Gen 2 is slightly thinner so it fits differently in my opinion.
