Hadrono Smart Health Wristband, Wearable Health Fitness Tracker, 120+ Sports Modes, All-Day Automatic Monitoring, with Pedometer/Improve Sleep/Stress/Health, IP68 Waterproof, 2 Pack Bands, Free APP

Randomly stopped vibrating. I woke up late 3 mornings!!! Trashed it!

I only used this for step counting. Had less than 6 months, and no it won’t hold a charge for more than 12 hours. When I first got it, it held charge for over a week.

Easy to connect with app and phone. Provides a lot of health and exercise data. I am not confident in the BP readings as they are always lower than the readings I get from I a professional BP monitor. It is light and I rarely notice I am wearing it. I remove before showering therefore I am unsure of the waterproof capabilities. I have used daily for about two weeks and am very satisfied thus far.

I was really in the market for a Whoop Band but had no desire to pay their silly subscription fees when I just wanted activity, heart rate, and maybe sleep tracking. A couple observations about this one: It comes on a silicone strap and also has a velcro strap in the box. Throw the silicone one away, it's useless. The velcro strap is comfortable and stays in place, just not sure how long it will last. So far, this tracker and its app seem very good. I do question the accuracy of the data, there's a lot of info gathered by this inexpensive little device and there doesn't seem to be a lot of variance. But the activity tracker is reliable and I'll continue to test things like heart rate, BP, pulse ox, etc. So far, worth the price.

Changing my review due to ineffective product. Product worked okay for a very short time and no longer works correctly, which led me to return it. The product was lightweight and felt good to wear. The touted features sounded good but in reality they didn't work as described. The accuracy went downhill quickly. Further, when setting up the app it requests access to your messages and phone records. Why does a seller need to access such? Very sketchy tactic to get your personal data—no company needs this. This is why I use a burner phone for things that require apps.
