When I first saw this pretty watch I knew had to buy it. And after reading the reviews. Seemed like a good buy.I also called my mobile carrier and asked it my A32 Samsung phone would be OK to pair with this smartphone. Directions said 4.0 or higher.My carrier said ther should be no problem with the two pairing.Watch arrived and the Directions said 10-15 days of service on a single charge.This watch has NEVER lasted that long. The most this watch has lasted was 37 hrs that was after the first charge. Then a little less after each charge.Now it's down to 22 hrs.The HR and BP and sleep are pretty accurate.I enjoy wearing this watch just wish it would last as long on a single charge as the Directions say it should. That's the only problem I have with this watch.Battery life is only 2-3 days. Watch looks great and is easy to use.I have a very tiny wrist and this watch still looked very good on me. I wanted something that looked a little dressier than your common smartwatch. This one was easy to set up, has different watch faces, and for the price, I think it works very well. So far I have encountered no issues and I was able to set it up without any problems. Just follow the directions and you should be done with set up in several minutes. I like the color and taking out the links so that it fits my wrist perfectly was not that big of a deal. I had my husband help me and it only took a few minutes. This was a good purchase for me. Very happy.So far it works okay.Impossible to make smaller, bad reviews on app so returned??‍♂️??‍♀️ Great watch for tracking steps!I appreciate the adjustment allowance this watch offers! I have pretty significant wrists (size) and most watches, even with extenders fit pretty tightly.The instructions stated that immersing in water may cause damage. Most fitness equipment is universal and designed to withstand all elements. I have worn the watch in the shower and while washing my hands and have not noticed any changes in appearance.I downloaded the app but did not feel the app was very secure or fully developed.This watch is beautiful, Looks like a piece of jewelry, very delicate and elegant. Real women’s watch. It’s all metal. Sizing the watch is easy with the provided tool to remove the connecting pins. Easy to set up after downloading the app. Has many different watches faces. Great smartwatch and fitness tracker. Has features include blood pressure/heart rate monitoring, blood oxygen sensor, call and message notification, music player, alarm clock, stopwatch, trackers for a pedometer, calorie intake, distance, daily workout list, brightness adjustment, inactivity monitoring, and a sleep mode.
