feifuns Smart Rings Wearable, Fitness Trackers with Multiple sport modes, Sleep Tracking - Heart Rate - Blood Oxygen - Blood Pressure - IP68 Waterproof, 24/7

From description had relatively high hopes but sadly disappointed. I ordered silver and the black version arrived!Well packaged with nice charging box. Also supplied with charging cable for initial 60 min charge.According to Amazon description there are 4 sizes but in reality only two. Even small I ordered was a little large for me but fit was acceptable.My disappointment was confirmed when started to use. It aims to measure exercise steps, blood oxygen, blood pressure, heart rate and sleep tracing. The steps are tracked in the background but you have to manually trigger blood oxygen, heart rate and blood pressure from with the iPhone app. Not really optimum when my watch measures these (except blood pressure) continuously. In addition these metrics cannot be synced to Apple Health although advert appears to suggest all metrics cannot be synced.The heart rate and especially blood pressure were not accurate. Decided to send it back and would not recommend. Get what you pay for!

A nice fitness tracker, does all it says on the packet! A good price, the battery lasts a whole week. I would recommend.

Good in every respect, including workmanship, durability, etc. The ring is very light, and you can't feel it on your finger. After pairing with the application, everything works as it shouldThe number of functions is not overwhelming, and the sensations are correct. I compared them to the Samsung Classic 6 watch. Sleep tracking is also lovely. If the price suits you, I recommend it.

This smart ring is a nice looking ring. It's thick but actually just looks nice on. I'm not sure if it is more gimmick than useful, but in my testing over the last week I found it to be very good. The charge does last the week for sure, possibly a little longer. The little case it comes in charges the ring and the USB lead supplied then charges the case. It's actually a really nice case and a really nice looking ring too. It was ever so slightly too large to wear on my wedding band finger, so I put it onto my other hand and I wore it there for the week. It's comfortable and looks good.But what about its functionality? You download an app to your phone to use the ring. You then put the ring on and pretty much forget about it. It automatically monitors, walking and sleeping. I found that the overall sleep time was very similar with my Samsung watch. But the waking periods, as well as the light and deep sleep were very different to my watch. I found it not to be as accurate with regards to what type of sleep you have, but will be fairly good in recording when you are sleeping. The number of steps recorded on the ring was also quite similar to my watch over a typical day. I recorded a 5K run, which you have to use the app on the phone for. I opened up the app, selected the activity, clicked start, put the phone away and then the ring is meant to record all the details of your run but it didn't record the distance. I'm guessing that's done via the phone on the two runs I did. Because I needed the phone for activities other than walking and sleeping, it did make me wonder why I wouldn't just use the phone. When recording the run, leaving the phone in the car, no distance was recorded, so that was disappointing. Heart rate was fairly accurate within reason, but the blood pressure measure was not accurate at all. Most watches will not accurately record blood pressure anyway, so there was no surprise that this device had the same difficulties.So overall, a nice ring that looks good. It monitors your steps and monitors your heart rate. It also monitors your blood oxygen levels too, all fairly accurately but as an activity tracker, it's not so effective without a phone.I think this ring might actually be early development as a wearable activity tracking ring, and so expect to see ongoing improvements in time. If you are an early adopter of this technology, you might actually like this ring. It has some good features and actually looks quite good.

From morning workouts to evening relaxation, this smart ring has seamlessly integrated into my lifestyle. It provides invaluable health insights without intruding, and features like remote photography add practicality. Its sleek, comfortable design makes it a joy to wear. A standout for anyone looking to prioritize health monitoring without compromising on style or convenience.

This smart ring has become an integral part of my health regimen. Its accurate tracking of steps, heart rate, and sleep quality provides me with insightful data that motivates me to stay active and improve my overall well-being. The sleek design is comfortable to wear all day, and the battery impressively lasts up to five days on a single charge. The ring's notifications are discreet yet effective, keeping me informed without being intrusive. Overall, I'm highly impressed with its performance and reliability. It's a fantastic choice for anyone looking for a smart wearable that combines style with functionality in monitoring their health

The media could not be loaded. First off, my expectations weren’t very high. The price, unfamiliarity with ring technology and the fact that I don’t like wearing rings all lowered my expectations from the get go. With that being said, let’s begin. The ring is very light and comfortable. No irritating sharp edges. Charging case is very nice. From my initial testing, it’s been accurate. Blood pressure readings were best spot on. Battery life is decent. You’ll get about 3-4 days before needing to charge. It looks very good. Now here is where things gets a bit disappointing. The only thing that appears to sync dat for Apple Health is the Steps. Those that interested please refer to the video. It’ll show that blood pressure and heart rate don’t appear in data sources however steps do appear. I suggest that the developer of the ECTRi app work on those integrations for Apple Health and all other pertinent reading categories that aligns with Apple Health. However the in and app works with this ring and has these features. Or am l missing something that turns on these functions? Developers please let me know as I’d like to fix this because if not then I may be returning this ring sadly.Other than that

I like the ring but getting to registerthe ring to its APP is impossible. Keep getting error message. Customer service tried to help but to no avail. App is full of bugs and not useful.

It does exactly as the $400 rings do it will measure your stress level, your oxygen level, your beats per minute and some other tracking with walking, etc. One of our rings works perfect the other one will not charge. No product support. If you get a good one it works great….if you get a bad one it’s worthless.

App is ECTRI on google Play

The app doesn’t work
