Lenovo HX03 Cardio smartband is a decent band. proper heartrate sensor, proper step counts, calorie counter, good vibration for calls and messages. only drawback is battery backup which lasts up to 6 days but it is ok factor.

A fantastic smart band with attractive features like pedometer, measures amount of calories burnt, steps walked, heart monitoring and a digital wrist watch with date & day as well. Loving it!

After 6 months strap broked and i don't know whether it is available or not

fantastic

It's a fine product but the main issue is only for the battery,The battery dies very easily..
Rather than that everything is very nice

Nice product

it is very good watch.

Awesome product. Value for money.. 💰

Smart band very good but battery drain easily and steps counts more.. It is not 100 % accurate

1. works fine just doubt the accuracy of steps I took 3 rounds of our society (quite a big one) it recorded 11k steps in whole day I think it should be around 8k max and corresponding distance travelled
2. decent battery life
3. durable build
4. no issues in connectivity with either iOS or Android
sleep time is rigid and sometimes records inaccurate data regarding sleep
