FITVIIFitness Tracker with 24/7 Heart Rate and Blood Pressure Monitor, Blood Oxygen HRV Sleep Tracking Smart Watch, Calorie Step Counter IP68 Waterproof Pedometer Activity Tracker for Women Men Grey

First, a big "thank you" to Amazon for authorizing return on several watches that were not satisfactory. This one is great! Looks like the FitBit Charge 6 at a fraction of the price and does excellent cardiac tracking. All instructions are in English! Pairing was a no-brainer. It is so comfortable to wear that I sometimes forget I am wearing it. Tons of FREE watch faces, including customizable. Can fine tune blood pressure readings.I am a competitive power lifter, and one of the watches I returned was nice, but the face was so big that it left a bruise on my wrist when I lifted the barbell. This one fits perfectly and looks nice enough to wear anytime.The only reason that I didn't give it five stars is that I have not tried it while sleeping. I am such a light sleeper that a watch will keep me awake.The app is amazing, with more choices than I have ever seen - even to setting the sensitivity.This company deserves to go to the top!

The watch will display the daily sleep time and deep sleep time, but this daily result does not usually transfer to the App. I contacted customer service for help, but their suggestions did not eliminate the issue. Oddly, the App data does seem somewhat accurate at the week and month duration. Also, it doesn't work for off-shift workers as well as they advertise. I worked second shift for the first three weeks of use, and the sleep data was terribly inaccurate. If I got up for a couple minutes to let the dog out, it decided I was up for the day even though I just got to bed a couple hours earlier.The pedometer seems to count high compared to my iPhone. The iPhone pedometer seems more accurate when I compare a known dog walk distance with each pedometer distance.The heart rate monitor does seem accurate enough, although I haven't worn it for an official workout. I am a blue collar worker and the heart rate monitor correlates with more active movements at work.I am uncertain of the accuracy of the blood pressure monitor, but it seems to be pretty close to what they read in the doctor office.The oxygen level accuracy seems correct.There is a page on the App for HRV data and the Lorenz scatter diagram. I am unfamiliar with what they represents.Years ago, I had a Fitbit. I remember being able to download all of the information to my computer. I don't think this watch has that option. It looks like the App will store up to one year of information. There isn't a calendar to be able to pick more than the previous few days for detailed information. It might be capable of doing more, but the instruction book is very limited and barley covers setup let alone uses or troubleshooting.

While i loke the band, feela lightweight. However the Gray Band cannot be cleaned of smudges. Works fine as a tracker. The H band app that u have to use is a little wonky. Took a lot of back and forth to get into the app. Overall good value if looking to keep track of basic items

I like that I am able to check my blood pressure but probably the reasom I am having problems is it is not hooked to the internet have to find out how to do that

This fitness tracker does exactly what I want it to do - track my steps. I don't care about it tracking my sleep patterns or heart rate (although apparently it will). I have had no issues with charging it - it hooks right up to the magnets. I need to charge it every 3 days. If you need all the bells and whistles you might want to purchase a FitBit, but to just track steps, this watch is great!
