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.

Comfortable fit. Packages were crushed during delivery. Need to exchange other ring in order for bigger size.

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

I would like to see the entire sleep data for the night and not just a portion.

Comfortable and accurate, received in 5 days.

Easy set up. I'm excited to use it.

Quick shipping comfy

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.

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