Tips:How to get the accurate blood pressure?
1.The blood pressure is not constant and will have a little difference at different times of day. We suggest you to keep sitting down status and meassure the blood pressure more times to take the average value.
2.The blood pressure test result by this watch is for your reference only. It has an error range of 5%.As a reference,fill in your pressure value( which was tested by medical instrument) in the APP "VeryFitPro" can make the data more accurate.
3.Please make sure the watch touch close to your skin when measureing the blood pressure and wait enough time until the data becomes stable, you will find that the data will be more accurate.
4.You can refer to the user's manual or contact the seller directly for help.

PROS:
The pedometer is highly accurate,calorie burn counter is very helpful.And I especially like the sleep monitoring function. As far as I can tell, that is very accurate as well.
You can pair it with your phone to receive text messages and calls.It will buzz and I loved how it vibrates if I get a notification or call so I don’t miss anything important!Even when I was riding my bike and could see or got an important call right on my wrist. It will tell you who is calling and the first few words of the text.
The sedentary alert has spurred me into action a few times now. I like that you can set the hours within which it will alert you.
I am not especially technically inclined, but i had no trouble syncing the watch to my android. I like the VeryFitPro app's user friendliness. So far, I'm very impressed with this product, especially for the price.
CONS:
When charging, there is a red-light indicator that turns off to show when the device is completely charged. I think my battery life will be more like 5-6 days as opposed to 7 days.But its enough for me.

UPDATE: The seller said there is no way to keep the time on the screen all the time. It's not a deal-breaker, but an annoyance.
The heart rate monitor and BP are not accurate if you wear the watch with the screen facing up like a normal watch. However, I read that if you turn it around with the screen facing the inside of your wrist, it is more accurate, so I tried it and it is closer, but still not convinced it's totally accurate.
My biggest complaint and this IS a deal-breaker. The app for the cell phone does not work properly. I have an LG Phoenix 4 Android phone. I use bluetooth on my phone for headphones and handsfree calling in my car, so I can't always have bluetooth connected to my tracker. I prefer one that uses wireless syncing like my old tracker. This is not specified in the description. When installing the app, it does NOT put an icon/widget/shortcut on the phone's screen so I have to go into Google Play to open it. I lost all my data from yesterday when I tried to reconnect and sync this morning to see what my sleep pattern was like. You cannot see the sleep pattern on the device itself. If I cannot get the app issue resolved, I will be returning this device. Without a working app, it is useless.

I had a pretty good idea of what I was buying, but I was still pleasantly surprised.
Expectations:
- Good: Heart rate tracking
- Very Good: Steps tracking
- OK: Blood pressure testing
- OK: Sleep monitoring
- OK: Notification alerts (but low expectations there)
- OK: Display
- Good: Battery life - expecting at least 5 days
Reality:
- Very Good: Heart rate tracking (Tip: Start an activity for continuous monitoring)
- Excellent: Steps tracking - I did a >5000 step walk today and this only differed from Google Fit (which has proven trustworthy for me) by a few steps.
- So-so: Blood pressure testing (Tip: CALIBRATE BEFORE FIRST USE and CALIBRATE OFTEN)
- Very good: Sleep monitoring. I’ve been through sleep studies and this correlates well.
- Very good: Notification alerts. More text than I expected was displayed.
- Very good: Display. Quite attractive and clear. (NOTE: Barely readable in daylight, even at brightest setting.)
- Very good: Battery. After 24 hours of heavy use it is at 89%, which should allow for a solid 7 days without letting the battery completely discharge. I like the charging method since it doesn't require a cable, but you'll need a USB-A port available.
Caveats:
- There doesn’t seem to be a reachable company behind this Chinese product besides their “YM USA” Amazon Storefront. For instance, I always like to download a digital version of manuals, specs, etc. After diligent searching, I couldn’t find anything. On the other hand, they seem responsive to questions and feedback.
- As an information security professional I have extremely low confidence about their data collection and handling. Include this in your evaluation of cost vs. risk. The company may have wonderful people working there, but if Chinese intelligence says, “collect this data and don’t ask questions”, it will happen. Even if we ignore the risk of deliberate espionage, if they accidentally leave all your data exposed on the Internet, you will have no meaningful recourse.
The data available includes:
- Your location. For instance, military operations have been compromised because of “hot spots” of fitness data in unexpected locations.
- Your locations reveal a great deal about you, your interests and beliefs, your friends and associates, your work, hobbies, and habits, etc.
- Your contacts information. (If you allow SMS and SNS alerts.)
- Your health. A great deal about your health can be inferred from your activity, biometric data you enter, and biometric data collected. This is useful on a personal basis - presumably that is why you are looking for a fitness tracker, but information is power, and in the wrong hands can be used against you, your company, and your country in many surprising ways.
- Your camera and pictures (if you use the camera control part)
- Your files. I’m assuming this is required to write and read the app information, but it may be far more intrusive.
One interesting test I did involved deleting the app storage, uninstalling the app, then reinstalling the app. I had to pair the tracker again, but after doing so, all the data restored with the exception of some of my settings. That means it was probably stored elsewhere - probably in China. (Another possibility is that data is kept on the tracker even after syncing with the app, but this seems less likely due to the very limited storage on the tracker.)
The inability to reach a real company is probably not a big risk for such a low-cost product, though it is annoying to not be able to download the documentation. The security implications are worth considering more carefully, especially if you are a researcher, in a powerful or high-trust position in a company, work in higher levels of government, are in the military, etc.
The mobile app has a pretty good design, but again, I knocked off points for security. Let's face it. The Internet Of Things is a security nightmare, but most of that is incompetence and complacency. However, where nation-states have demonstrated their willingness and ability to siphon off incredible amounts of data and weaponize that data, security needs to be in the forefront of every purchase and product use consideration.
