Advice for syncing

I spent hours trying to connect and found this advice by googling
“After an hour or more of frustration I finally was successful in connecting the wristband to my wife’s phone. I removed any pairing in IOS that I had created in earlier attempts. Then in the Lefun Health app on the Health screen I went to the settings screen via the three horizontal bars list icon in top left. The next step was the key to success for me. I changed the display on the wristband to the one after the calories display. It looks like a magnifying glass and old mobile phone (search for phone?). With that displayed I returned to the app screen and selected Search device at the bottom of the list. The connection was almost instantaneous. I was then able to see the wristband info, save personal data and synch the device with app. It would have been helpful if the instruction sheet had included a picture of the proper display prior to the search process.” Also, after you “search”, a # will appear on the top of the screen (same MAC # that is on your watch), you must click on that # on the search screen to continue with syncing)

Don’t understand the negative reviews

I bought this smart watch on Wish for about $4, while yes, the instructions didn’t specify how to charge it, I was able to find the information by a quick Google search. I’ve only had the watch for a day and I’ve really enjoyed it! I’ve been able to tailor it to my liking (changing it over to British standard so everything is in lbs etc). For $4 I would say just getting the message and alerts is well worth it, plus being able to turn my wrist and see the time is nice (which of course you can do with any watch but hey, even some standard watches are more than $4) but would I have purchased it for a higher price? Probably not. I haven’t found anything wrong with it yet, but if I end up having trouble, I’ll definitely edit my review! But I figured I’d write one while everything is going well to give this app a fair shot. It’s pretty cool!

Consistently Incorrect BP, HR, & SpO2 levels

I received this watch as a gift and I was incredibly excited and grateful, as I have multiple chronic debilitating health conditions that require close monitoring of blood pressure, heart rate, oxygen saturation and to monitor overall sleep patterns(or lack there-of). However, I have consistently found that the product is continuously out of range and exceeds sometimes more than 10-20+ points out of range, and I am certain due to the fact I am monitored at multiple specialist physician offices! Now to give it the benefit of the doubt, I tried flipping the watch to the inside of my wrist to see if the radial vein or artery would give a better reading, but that didn’t work either; instead it left me with spotted welts which leads me to believe the product is using laser or infrared technology to monitor at unsafe levels. So it begs the question, is this device safe? What type of sensor is being used to monitor bodily functions? And is this typical for your product, or do I just have a defective product?
