WAFA Fitness Tracker with Heart Rate Blood Pressure Monitor, Waterproof Sports Smart Watch, Bluebooth Smart Bracelet, Sleep Sports Data Monitor Activity Tracking Pedometer Watch for Kids Women and Men

Dropped my rating from 5 stars to 2After 1 dayI bought this watch specifically for the passive blood pressure monitoring, after I got a reading of 189/119 on a manual pressure cuff during my DOT physical. I found that hard to believe, as I use my old Samsung s9+ to test my BP periodically, and it averages 129/75 on that app over 4 years of data.My first reading on this watch was 117/80. I immediately checked my BP using the Samsung phone app and it was 125/79. Pretty close. I had to run some errands so I stopped at a CVS while I was out and checked my BP using the watch on my left arm. It said 119/79. Then I removed the watch and checked my BP using their public machine and it gave me a reading of 123/82. I took another reading from the watch after putting it back on, and got 121/81.I had been wearing the watch for about 90 minutes when I got home, and the passive BP readings of the watch ranged from 111/76 at the low and 127/81 at the high. So I decided to do a test - I chugged 6 beers in one hour, and smoked about 5 cigarettes.The watch registered my BP as 119/79 before the first beer, and 138/88 after the sixth. So it definitely detected something.Then, I decided to cut the grass. It took me 45 minutes. The watch measured my BP as 127/81 to 138/89. I had nothing else to compare it to, but that seems believable.The step counter also proved to be pretty accurate. My back yard is 62ft across, and it took me about 30 passes to complete it. My steps when mowing are about half my normal walking stride, roughly 13 inches. If you do the math, that equals 1,717 perfectly equal steps. The watch counted 1,817, which makes sense when you account for the steps spent turning the mower, beginning and ending the task.The only thing I found that is not very accurate, at least not while active, is the heart rate monitor. After drinking the 6 beers, the watch was saying my heart rate was 112 bpm - I verified that with my Samsung phone which showed 114. However, once I was out there mowing, and sweating, the watch showed a remarkable decrease in heart rate, going from 112, down to 71 right after I started, and then bouncing between 76 and 91 during the entire time I was mowing. The lowest reading it took during that time was 54 bpm. Definitely don't agree with that, at all. However, I don't have a second data point for comparison... So it could be right, but I highly doubt it. It's my opinion that the HR sensor works well when dry, but once you begin to sweat, it gives false readings.The O2 sensor, however seems pretty accurate. My Samsung phone almost always reads 100% saturation, occasionally 99%. The watch reads a steady 98% during rest, but while I was mowing it deceased to 96% when I was finished. After 10 minutes of rest, it was back to 98%.I hope this information is useful to someone else looking to purchase this watch for the same reason I did. While I don't claim the BP readings are 100% accurate, they ARE, however, consistent. And that consistency seems to be reliable enough to use the watch as a gage, albeit not an actual medical device.After 7 daysOn day 3, the power button stopped responding reliably. Sometimes it'll work, sometimes not. Sometimes you have to press it two, or three times, sometimes one. Sometimes really hard, sometimes not.On day 4 the heart rate sensor stopped working reliably. When it works, it works fine. But there are certain times where it just stops working for several hours. This wouldn't be that big of a deal, but the watch vibrates every time it doesn't detect a heart beat. So every 30 seconds, it's vibrating and turning the screen on.If you have do not disturb turned on, the watch will turn that off when it doesn't detect the pulse, in order to vibrate and bother you. The only way to stop it from vibrating is to take it off and throw it across the room.Also, there doesn't seem to be a way to power the watch off. Sure, there's a power option in the settings to "shutdown" the watch, but that doesn't actually seem to work. When you attempt to shut it down, it just turns itself back on after some time.The sleep tracking is also useless. If you sleep at a regular time, like 10pm to 7am or so, then it kinda works. But if you sleep at odd times, or if you have an irregular sleep pattern, then the watch will literally just make stuff up. It says I was asleep for 7 hours while I was unloading trucks in a warehouse. The sleep data is just fake.

Perfect for my 7 year old grandson. He wears it daily, keeping track of his steps and activities.

(Update after 1-1/2 years of use: The watch's heart rate tracker now doesn't accurately show my heart rate on a treadmill or stationary bike. I have checked it against the machines' heart monitors as well as counting my pulse with my fingers. The watch rarely shows over 90 beats per minute, but the other tracking methods show as much as 120. When I check my heart rate history later with the phone app, it doesn't show more than 75 or 80. Otherwise, the watch works as well as it did when new). (Now back to my first review): This tracker met most of my expectations for features I wanted most: checking heart rate and blood pressure. The heart rate tracker matches closely enough with detectors on gym treadmills, pharmacy machines, and two-finger pulse counting. It sometimes gives false alarms for spikes in heartbeat, mostly with sudden movements or burying my wrist under a pillow while sleeping. It also takes a few seconds to catch up with your heart and with exercise equipment monitors while exercising. The blood pressure monitor is a few points off from true readings, but close enough to be useful, at least for me. Sleep tracking seems accurate enough for my needs because I pretty much already know when I fell asleep and when I woke up. It often mistakes slow-waking breakfast and coffee time as sleep, and I haven't yet figured out how to set it for daytime sleeping. If you need hour-by-hour and daily records of health and exercise factors, the phone app is a handy tool. I don't use the step counter and sports-tracking functions much, but they seem reliable. The text message, phone finder and stopwatch functions also work well. The phone app is fairly easy to interpret, although I still don't quite understand how and when it shows health results. For example, it takes a few minutes after activation in the morning for sleep results to show. The Bluetooth connection is pretty much set-and-forget. It does, however, annoy me with lost-connection warnings if my phone happens to be out of range in another room. There probably is a way to disable the warning, somewhere in the instruction booklet. I confess I haven't made it completely through the booklet, and there are several functions I will never use, so I'm not interested. The instructions are clearly written in close-enough English, and there are illustrations to help you understand. That is several steps above instructions for a Chinese-made tracker I had bought earlier. Altogether, I can recommend this tracker, even though I'm not quite ready to give it 5 stars. I haven't been disappointed.

Some days, the Hband app is not a battery hog, but other days, it almost drains my new iPhone 14 battery completely. I’ve rebooted the phone and the watch to no avail. This has happened 50 or more times and continues to happen. I would not buy this watch again....6/2/2023 - I have played around with the Hband settings and found that the "Find Me" function is the culprit. After disabling it, the Hband app no longer bleeds the iPhone battery dry. I am updating the overall rating to a 4 because the watch is a pretty good value for the money.

My wife loves taking her blood pressure with such ease

Works great but they don’t last long as the thin piece by the clasp always breaks! They don’t have a replacement band so you always have to get a new watch. We have had several of these as my son has a condition that we need to monitor his sleep, heart rate, and blood pressure and this watch covered all that. Love it for that but I hate the broken clasp problem
