Bit tricky measuring to order right size, had to go larger that ring dize, so ended up fitting on different finger that planned.

Quick set-up and easy to use app

The set up is easy. The app gives the option to change measurement methods (ie- pounds/kg). You can also choose what you want turned on (heart rate, sleeping, pulse ox). My only problem is the sizing. 6 of my fingers are a size 6 and I verified them using the size chart before ordering, but the ring barely fits one of my fingers. My hand has to be cold to get it on and off. I recommend sizing up as a result of my experience.

Quick shipping comfy

It is a little big but should be ok. 😊

Just got it so still new to it . Sizing seems a little smaller than expected. I have to wear it on my pinky instead of my ring finger.

So far so good my rings are charging. Good to actually have them in hand now.

I have had this ring for about 9 months. I did notice the battery going down much faster than the noted 6 days, usually only a couple. I asked Herz and was told to charge differently, etc. I did all the suggestions they had. I continued to use the ring but noted it did not capture exercise like it did when new. Again, contacted and they ended up sending me a brand new ring. While the ring was not quite as I expected, the customer service was great. I am currently charging my new ring and will let you know :)

Comfortable and easy to set up. Too bad I have take it off every time I wash my hands. But otherwise, I like it so far. Only had it for a week.

Easy order thank you

Customer service responded quickly and replaced my defective ring. I look forward to using this ring and the app.

It’s a beautiful ring and I like the fit.

Fits well. I sleep with the ring on with no problems. Easy set up!

Quick shipping / I measured but not sure it’s tight enough - but the next size down would be too small For my index finger

Good experience so far

Just received. Need to try it out

Don't know yet so I have to try it and see

Just got the ring so I cannot leave a review as TJ how it functions. As for the ordering and delivery that was a smoot and easy process.

Battery life is not 10 days. It’s almost 7. Although purported to be water resistant, quick start guide says to dry promptly if it gets wet. Seems just fine in every other way

Excellent customer service, quickly replaced wrong sized ring with accurate size for no charge. Did not need to send wrong ring back. App easy to set up and use, but only measure heart rate every 30 minutes from my understanding which isn't ideal when trying to track it regularly.
