Sprinto UM4 Smartwatch Digital Activity Tracker Band Wristband with Daily Step Count | Heart Rate Monitoring Compatible with All Smartphone Device (Assorted Colour)

Worst product i have ever seen . Every thing is fake. Firstly, when i opened the outer box i saw that the packaging was tampered. After opening the box i saw some scratches on the watch . Then i tried to turn on the watch but it didn't bcz it wasn't charged . So when i tried to separate the screen from band , the screen got broken . Battery life is poor. Screen quality is poor . Waste of money . Dont buy this product.

This product is conpletely useless. It is not even recording any heart beat or spo2. Range of values for every option are stored in it. And it is displaying that only. It is showing heartbeat for chair and non living objects as well

Bad product. Doesn’t give accurate readings. Stopped syncing to app. after a few months. Waste of money. Not recommended!!!

Very bad product. Once returned and other piece also worked once then same problem. Even charging not done. Its It's completely shut down.

Not Charging. Not working. Cheap packaging. No Manual.

I think this company gives bad products.The watch does not contains any polythene wrraping or polythene screen guard.Battery life is of 1 hr after charging 5 hrs.

We can sync this watch with YOHO app, after configuration it will provide all the data like step count , heart beats, Sleeping hours. nice product within budget

Thw product didn't even boot when i recieved it ...... N there was no charger in the box .... Photos of the dilevery i got is attatched there is nothing else available in the box other thatln the photos attached
