About this item
- 【Size Before You Buy】Before purchasing the POYIPI Smart Ring, we highly recommend that you purchase a ring sizing kit to determine the most comfortable and suitable size for your finger. Please note that this size kit is only compatible with our smart rings.
- 【Why to Buy the Ring Sizing Kit】Many people are unaware of their suitable ring size, as manual measurements often lead to inaccurate results - resulting in ill-fitting rings that are either too large or too small. That's why we have designed this ring sizing kit to help customers find their perfect fit.
- 【Product Material】The rings in the ring sizer measuring tool are made of plastic and only as a sizing reference when selecting the right ring. This tool is designed to assist customers who are unsure of their ring size in selecting the most comfortable and accurate measurement for their smart ring.
- 【Choose A Finger】Ring sizing tool works on all fingers and can be worn on either hand. For optimal accuracy and comfort, be sure to size the exact finger on which you plan to wear your Smart Ring for the best fit!
- 【How to Choose】It is recommended that you wear the ring for at least 24 hours to confirm size and comfort. A ring that stays securely in place without slipping off or rotating during regular activities is considered the correct size.

Excellent buy, readings typically right on the money
Greg—March 26, 2025
The ring runs just a little big but easy to set up and wear. The main thing that impressed me, is you can adjust the ring to get a more accurate BP readings. Ring preset is 120/80. I had went to Dr. day before and got a reading of 100/63. I came home and took readings and the day ring received. Based upon an average of 103/65, Calibrated the ring program. Readings on ring closely correlate with BP machine. Hope other rings and watches incorporate this tool. Highly recommend! The other features coincided with my Samsung smartwatch. Read more

Nice But Beware.....
Placeholder—May 29, 2025
I purchased the silver color but didn't realize it has a satin finish. Due to my working environment and hands on duties the rings finish has visible scratches which cannot be buffed out. I'm very satisfied with the overall fit, health app functions and extended battery life after minimal charging time. Read more

Works great
Snow Bird—June 17, 2025
The smart ring works well but not sure if the blood pressure is 100% right on. When my blood pressure is high The ring will low blood pressure reading like 117/79 but like last night my reading was high 131/86 and I knew it would be because I skipped taking my bp to see if it went high and it did. The BP going to take time or try to understand it Read more

Your mileage may vary
Seraph_Darknon—April 21, 2025
It is generally slow to sync and but sends metrics to Apple health without a hassle. Worked fine for about a week but stopped charging/pairing at about eight days. Replacement ordered, and will see if this was just faulty. The app is also intuitive and works fine. Read more

A product that actually lives up to its description. My ring fit perfectly and does everything that was written in the description. I’ve showered with it on without any issues. The data that it collects has been accurate. Ive only had it for a month but I’m very pleased with my purchase. Read more
