I’ve tried at least 8 other watches (pricey) before this one but this is the VERY BEST — style, price, syncing, and uses. It took about 15-30 seconds to pair with my iPhone after I downloaded the app. It’s easy and accurate measuring my blood pressure and my pulse. I have aFIb so it’s necessary for me to track my health. This one does quickly, accurately, and stylishly. I doubted how great it would be because the price is below $30. I’m so glad I decided give it a try and wasn’t disappointed. My only negative is a tiny issue with the band. It’s really large on my wrist but it has enough holes to tighten it sufficiently. If you’re on the fence, please give it a try. UPDATE: The charged life is phenomenal. Today was the first time it needed recharging and it still had 2 bars! Read more

This is great as an inexpensive $25 step counter watch. 4 stars for that, but I’m gonna pack a bunch of cons for that one missing star. I’ve worn it for a week and will wear it for another week before I decide to return it or give it away. The blood pressure and heart rate consistently come in about 10 points lower when comparing to a blood pressure cuff and oximeter, but close enough to be in the ballpark. The O2 saturation comes in 1-2% lower than the oximeter. Exercise has a few activities to estimate calories burned, but seems way off. For sure I burned more than 42 calories on a 30 minute walk. Step counter seems very close to agreeing with the iPhone step counter when I use both. It vibrates when I have an incoming call. I can send it to voicemail, but can’t answer the call. Messages has my last 3 fb messages, but those are old and it doesn’t have today’s recent sms text messages. Maybe my fault in setup. Weather and camera do nothing. Player plays whatever is queued up on your phone, in my case a podcast. Had to open music on my phone, play and pause, then could unpause from the watch. Don’t see a way to use earbuds or AirPods. Timer worked, find my phone didn’t work. Settings were basic, like mute notifications and adjust brightness. Instructions included were printed so small, I got a magnifying glass and still couldn’t read it all. We are talking mandarin on a grain of rice small. Annoying that half the time, when you raise your wrist to just check the time, it doesn’t turn on. You have to shake your arm or push the dial. It has a single push/turn dial. It will light up randomly while moving around in bed and trying to sleep. It goes to sleep in 5 seconds. It goes off before I can hit a button. Again, that might be me missing a setting, but if so that setting is hard to find. It has an app called Hero Band III. It works with iPhone, but the data doesn’t auto feed into Apple Health. That’s what I wanted and probably will be my deciding factor to return it, cave and just get an Apple Watch. Read more

Awesome product. Bought it for BP measure, very accurate when it comes to BP readings. Great on the HR, great on the Oxygen levels...Would buy it again no issues. Would I recommend this simple to use watch..Absolutely 100%. For the price you cant go wrong. Battery lasted 5 days. Read more

The only thing accurate is the statement "This is not a medical device." Pros: 1. Inexpensive 2. Tells time & weather 3. Player function works with your music apps 4. sp02 readings seem reasonably close but inaccurate. 5. Find Phone feature may be handy for some folks. It makes max volume noise on your phone to help you locate it. 6. Long battery life, lasted over a week before needing a charge. 7. Waterproof Cons: 1. BP & HR readings are comically off. The 'graphs' displayed are merely the same static watch image. Tested against ambulance & hospital monitors and 'close but no cigar' is as good as it gets. Must be worn on inside of wrist and held firmly against the skin at your pulse point to get anything even remotely close to accurate, otherwise readings of around 50% are standard for heart rate. 2. No watch faces with the HR, BP & sp02 readings visible, only the incredibly inaccurate step counter & equally useless calorie burn count. 3. Pedometer counted 2000 steps while I was laying in a hospital bed, 5 feet from a bathroom. If I actually hit 200 that would be a shock, let alone 2k. 4. No way to delete erroneous readings, so the continuous heart rate monitor 'average' is completely useless, and the BP & sp02 data history is not very helpful either. 5. Camera control does not work with your camera apps, Heroband uses it's own internal camera function with no adjustable settings besides front/back camera. 6. 'Timer' is not an adjustable countdown timer, it is merely a stopwatch, and if you change screens or turn off display it ceases to function. 7. Notifications only work with a few social media apps, none of which I use, Google Calendar is not supported and selecting 'Other' continually floods the watch with beeps, buzzes & unexplained RAM, battery life & device temperature data. Disabling that setting once turned on is not easy with nonstop pop-ups taking over the watch. Whether that data is your phone or watch is never exactly clear either, it just reports data that neither phone or watch reflect. 8. Messages is nothing but the above RAM/Temp/Battery readings without the pop-ups & nonstop buzzes. Does not work with Signal, but may work with standard phone built-in SMS app (could not test since I only use Signal & Telegram). 9. Sleep monitor is not adjustable to your actual sleeping hours, simply monitors inactivity during arbitrary evening to morning hours. Reported 3½ hours sleep while I was wide awake but just resting & still. 8. Magnetic charger cable has a flaky, easily disconnected connection, watch does not charge off my backup portable batteries, but does if plugged in to a charger. TL:DR Cute, cheap toy, but most of it's functions are absolutely useless. If I wasn't hospitalized for over a month after receiving it this would have been returned immediately. Amazon should be ashamed this is their pick. DO NOT BUY THIS WATCH! Read more
