feifuns Fitness Tracker Watch, Smart Bracelet IP68 Waterproof Swim Watch Activity Tracker with Heart Rate Monitor Step Calories Counter Sleep Pedometer Watch for Men Women Kids/Android iOS

This is the third SmartBand I've purchased, and returned! All the bands themselves are great look good function as they should, however the apps suck!!! How can this have 5 stars and the app that makes the Smart Band work have two and a half maybe you should review the apps that associated with the smart things before purchasing so if you have a 5-star smart Band and a two star app do not buy it I've already started to return process I will not be buying from this seller again! Extremely disappointed this was a birthday gift thank you. 1 star.😝VB Greene.

This watch is a great product! A must buy! Good battery life and the app works well with my iPhone. It always stays connected with my phone. Of course as long as I’m in range of my phone. And the health trackers are good too! The band on it feels like a lightweight bracelet and it’s not bulky or in the way. I am truly impressed with this. Also impressed with how crisp and beautiful the screen is. Doesn’t look cheap. I give this 5 stars and here to say that it’s definitely worth trying!This watch works with iPhones and android both. 👍🏼

I loved it so much I got one for my hubby. Then my sis-in-law saw it and got one for her and my bro. It does heart rate, blood pressure, oxygen saturation, sleep, walking steps, walking distance, time. Needs to sync with my android phone to set time.Edit. After 2 months it lost sync with my phone and none of the previously successful resync tricks worked. I had gotten to really like the sleep feedback. Unpaired it still counts steps and take HR and BP but it can't save in the app. Without the phone app it can't report sleep at all. Very sad. Unpaired it also can't tell time.

Excellent functionality and water proof. Communicates well with the software and with Apple Health. Heart Rate measurement confirmed accuracy against blood pressure machine. Excellent customer service.

Keeps accurate time. Pulse and BP are accurate. Steps are way off. Oxygen levels are also not accurate. Would not buy it again.

Will not sync, nor will it connect to my android Bluetooth. Tried for an hour to complete both these task. Seems like a decent watch. Instructions are minimum, no happy with this product, will be returning soonUpdate:Finally was able to get the watch bluetooth to my phone and it now working and tracking. So far so good..will not be returning

Does everything it claims. Mine looses contact with my phone at about five feet. This may be my phone. I'm am disappointed since one of the reasons I got it was for emergency contact while swimming laps.

Very nice watch I really enjoyed it, the most important I was able to swim with it, love it!
