    I love all it can do, but it scratches easily. I wish I didn’t wear it all the time.

    I’ve been using this for about a month. It does a great job giving me an idea of how my sleep has been and if I have any breathing irregularities. My main issue is that you can’t edit an activity from a previous day. It does a good job of recognizing when you are working out but sometimes it gets the length of the workout wrong. If you don’t edit it that day then you can’t the following day. Others have complained about this as well. Hopefully a software update will fix this oversight at some point.

    Love the features and battery life is pretty good. Can go days without charging. After just a few months of having the gold version of the ring a lot of scratches and more tarnished than I thought it would have. Still would buy again.

    I bought myself one and this ring I bought for my significant other! We both love it! It tracks our stress, sleep, steps, activity, and so much more. We are even able to share our data with eachother.

    This ring exceeded my expectations in terms of the health information it provided. It was easy to get used to in terms of wearing it daily. I do wish they made more feminine options for females. The rose gold does look more gold than rose gold. It only needs to be charged occasionally and doesn't take long to charge.

    Reading up on this ring as much as I could before I purchased it was one thing, but going to a Best Buy store and hearing a sales person tell you about it, was better than just reading about it.
