ZapTech M4 Plus Bluetooth Wireless Smart Fitness Band for Boys/Men/Kids/Women | Sports Watch Compatible with Xiaomi, Oppo, Vivo Mobile Phone | Heart Rate and BP Monitor, Calories Counter

The product is the least accurate one I've seen in the market. While the seller describes the functions such as heart rate and blood pressure are for non-medical purposes meaning that the accuracy is low; one may expect error to be within 10-20%. However the readings are off my huge margin. The device shows my heart rate as 75 when it's 110 and BP as 110/75 when it's actually 130/90. (Measured this using actual medical device)Step count is inaccurate as well. It shows stepcount as 4000 when the actual stepcount is 7000+. (measured this using different fitness tracking devices and apps). The battery back up is horrible. Lasted me less than 24 hours on full charge. My recommendation is that, if you are serious about fitness, invest a few thousand rupees more and get a better product.

Battery life long time, and good product, Value for money

Quality is not worth the price

It's good

Nice watch but very fastly destroyed

The fit band connects with mobile via bluetooth but does not sync with any application in Google play. Not even with one they have mentioned. Since this does not link with applications, time is totally incorrect and hence of no use . I have tried with multiple softwares and multiple users and it did not work.

Good
