Unistore [All New 2019 Arival] F3 Rechargeable Activity Tracker. Bluetooth Waterproof smartwatch with 9+ Features Including Heart Rate,Blood Pressure,Step Counter,Calorie Watch and Much More-Black

Lefun Seems To Be Not Overly Knowledgeable Of Their Products Nor Customers Or They Were In A Hurry To Market This: When Questioned About Product, Unistore Stated The Two Queries Were "Sync Technology" Problems, Not Poor Android App Writing, Which This Electronic Engineer Spotted, Easily, As The Hardware Is All There: Time Uses HH:MM, But Can Use hh:mm For 24 Hour Mode, Like The Phone That It Syncs To Does, Just Like The Display On Time Can Be Done Via The App. Don't Get Me Wrong, It's Comfortable. It's Slick. It's Capable. But There's No Tracking Of The Oximeter On The App (Main Reason I Bought). I Don't Mind If I Need To Recharge Daily, Even, I'd Like Screen-time, At My Senior Age. Correct These Issues And, Man, What A Watch!

Basically I purchased this product to monitor my elderly mother’s sleep patterns. It is doing a great job for that. Also, the heartbeat and blood pressure readings appear to be fairly accurate. Again, I am looking at patterns and it is doing a good job. The step counting function doesn’t accurately capture her steps, but I believe that is an issue with her shuffling walk and not the device. It needs to be recharged at least every other day, which is more often than I would like, but not too terrible. In general I am satisfied with the product and would recommend it.

I really like how accurate the sensor is. It really measures my heart rate and blood pressure accurately. the joints are very tight but it gets loose over use and makes the product more longer-lasting . Really good for healthier body. Highly recommended.

Very slick and the quality of the material is very nice. I just started working out and this is the perfect watch. I am very surprised with the quality of this watch. Would definitely buy again once this one is worn out!

Seems like this could be a neat gadget- IF it would link to the app on my phone (Galaxy S7) so at least the date and time were accurate. I have tried EVERYTHING at least four times but will not sync, even asking community.... As much as I want to love this little thing, it's not cute enough to keep wearing as a bracelet when it doesnt do what it is supposed to (not heavy enough to use as a paperweight).

Started to glitch first day told me I was more than 30 feet from my phone when my phone was in my back pocket , but did take decent blood pressure reading close enough

Great for having on during runs, last quite long for a short charge. Very sturdy and feels great on the wrist.

The description stated the item was water proof. Forgetting I was wearing it, I jumped in the shower. I immediately thought to remove my watch. Doing so, I was thinking it would be fine. Wrong!!! The next day to present, it has no display... Money down the drain...,, Oh well for being water proof..
