Accurate sizing. Feels comfortable so far. Shipped quickly and I was able to correct the shipping address immediately with the help of customer service.

Easy set up and great value!

Good experience. Quick shipping

Fits like a regular ring. Still getting use to its functionality.

Really stylish and turn to size! I can't wait to have it and track my stuff! Thank you!

Took a little while longer to get than I was hoping but so far I like it.

Just received it so I love the look and fit so far

Arrived just as described and fits well.

I’m just setting it up right now.

Very easy setup, fit is comfortable, could be thinner for me as I can't wear it while sleeping but I already know I don't have the best sleep patterns. Very easy to read the app/results. Too many emails is only negative. So glad I bought this one and less expensive in addition!

Thank you for making Amazon delivery behave

Great value. Easy set up.

Very easy setup and tracking stats, comfortable to wear, great value

My main goal for buying a smart ring was to track my sleep statistics, and the Herz P1 does not disappoint. It shows me the total number of hours I slept, how many hours I was actually awake during that time, my REM sleep, light sleep, and deep sleep. It will even track my medical stats such as average heart rate, body temperature, and average blood oxygen all while I’m sleeping. Then it will take all of these numbers and give me a Sleep Score up to 100%. It is extremely comfortable, and I don’t have to worry about constantly checking my battery because it will let me know when I need to charge it again, usually after six days.
