MCNNADI Fitness Tracker with Blood Pressure, Heart Rate, Oxygen Level, Temperature Monitoring & Sleep Tracking - Includes 4 Additional Straps. Customizable Face, Activity Tracking, Remote Camera Control, Waterproof Pedometer Watch Review

This item seemed too good to be true for the price, and it was. This item was not working and could not be charged. The return customer service was excellent.

looks small, easy to adjust, but everything is very imprecise: temperature, pulse, blood pressure and oxygen saturation. The only thing that is accurate is the time and possibly the steps. I have a home blood pressure monitor that also measures heart rate, and I can measure heart rate while the watch is completely off.

Great Fitness Tracker. All functions work very well. My mom got it because she uses it to check her heart rate, blood oxygen, blood pressure and temperature and I'm going to buy another one. I used the app to sync all the features. Everything works perfectly. I highly recommend this fitness tracker from MCNNADI. Great price too.

Value for money is a plus. I don't find it bulky. I had little trouble getting blood pressure, heart rate, blood oxygen, temperature, and sleep metrics. Then I discovered that what matters to me is how I wear it. If I wear it as a regular watch, the readings will be questionable. Wearing it on the inside of your wrist is better for reading.

(1) Inaccurate. The measurements appear to be generated by a random number generator. (2) Poor design: you have to break the wristband to charge, and this caused the charging pin on my device to break after nine months, even though I used the device only occasionally and did not charge more than 15 times in total.

Rating changed. You must have just updated the app. It now has the ability to switch to imperial (not metric) system and temperature measurement in Fahrenheit. In general I am satisfied with the watch and this change - a worthy product for the money, especially since it is difficult to find a watch that measures the body. Tempo. It's simple and fairly easy to use. I wish you could set it up to stay on a specific screen like heart rate or temperature so you can just lift it up to see it during…

Used, in opened box sealed with tape. I wanted to try it until I saw the camera from behind. Called Revain to get a refund and let them know what happened. After two phone calls and an interview with a manager, I was treated fairly. I was told to either keep the watch or give it away or throw it away. I decided to check if it really works. This product is garbage. Blood pressure is off, temperature is off and the heart rate function doesn't work either. The only thing this watch can be useful…

Like "I spent a few days looking at the MCNNADI fitness tracker as it seemed to have more features than the others. I would like. The fitness tracker's blood pressure, blood oxygen, heart rate, sleep and temperature monitoring was really accurate, I have to say. Many trackers only have a heart rate/sleep monitor, but this one had all the vital signs. Connecting to the app was easy and I liked that it can track historical data. I wish the app could sync with more than one fitness tracker (watch)

Suits me! I love this fitness tracker and for the price I think it's worth every penny. Blood pressure, heart rate, blood oxygen and temperature worked well for me. I work in the medical field so I compared it to a $120 sphygmomanometer and found it to be 3 points up/systolic and 2 points down diastolic but for this price point and for a continuous monitor I think it isn't Deviation gives between 5 and 10 points is 100% acceptable. This watch is a guide and tells you when to see a doctor, and…
