GOY & KAY Smart Watch for Women Men, Smartwatch Waterproof Blood Pressure Watch Heart Rate Monitor Watch Fitness Tracker with Sleep Monitor Touchscreen Smart Watches for iPhones Android Phones-Black

This little thing is quite handy, bought for my wife. The heart rate and blood pressure were quite similar to our larger instruments. The only negative and why I rated it 4 stars is the Bluetooth feature doesn't work with her phone and the instructions provides are so small one needs a magnifying glass to read them. Had to go online and print readable instructions. For those not tech savvy it can be pain interpreting all the symbols used

Blood pressure is not accurate. It hard to get blood pressure and oxygen reading even following the instructions. The contacts for the readings are not placed very well, as such if you want to get a reading you have to press down hard against your arm.

Very nice watch for the money but very hard to understand programming!

Great watch for the money but it don't do the blood pressure accuracy very well ,app was good an no problem connecting it has many features justbwish it was more accurate it was way off

This product is okay if you want to be charging it every night when you go to bed. One of the things I liked was it monitor your sleep. How can you monitor your sleep if you have to charge it every night right around bed time. Also the other thing is when I do Dishes I have to take it off or it counts everytime I move my hand when washing the dishes. I definitely would NOT RECOMMEND TO ANYONE. SORRY TO THE SELLER!

I t works well

I had love the appearance of this watch however it work well for around two months and just stop working abruptly

At first I felt really good about this purchase but then I started having problems with the battery life. It wouldn't hold a charge for very long and finally after just 1 week the battery wouldn't charge at all.
