I followed the sizing guide, but it wasn’t the best so the size I ordered was too big. Customer service was great though and I was able to exchange for a smaller size easily. Fair warning though you will have to pay to ship it back. I just received my new ring and the fit is great. My only complaint so far is processing/shipping times. It is much longer than 3-5 days. However again customer service was great once I reached out about the delay in refunding me. So I had to give 4 stars for long processing of the return and lack of reaching out first when there was a supply issue and shipping took longer for the first order.

Only have it one day but the shipping speed was good with steady communication. The app and set up process is average. The fit was accurate to ring sizers. More to be determined after wearing it for a couple weeks and gauging the accuracy plus tracking with the app.

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

It's very unexpected to receive a genuine contact from a real person at a business these days. I was suspicious at first, but it was actually kinda nice upon reflection. Shipping was pretty quick, and I'm super excited to try my ring!

Just received. Need to try it out

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

My ring was too big, but I was able to send it back to exchange it for a different size. Overall that process was pretty easy, just took awhile!

It’s good love it

Stylish design and easy setup...

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.

The fit seems off. The first ring was very large and the replacement is too small for finger I had intended to wear it on. Customer service has been very helpful with the exchange.

Previous Herz P1 Smart Ring only kept military time even though set for normal time. Kept pretty good sleep pattern. I'm sure I will get good info from this ring.

So far so good. Just got it and haven't been able to truly test it yet.

Just got it and it was a fast delivery and so Easy to set Up.

Really comfortable fit going off the sizing chart! Looks great, Came with the charging case and just a regular cord!

Very easy to set up and looks really nice. Haven’t used yet but looks well made.
