Purchased THIS smartwatch bc I hate watches as they’re always too wide for my wrists, but LOVE bracelets!!! Nice, thin, dainty bracelets that don’t sweat your arm off. This option checked all those boxes.Not bright enough to see in the outdoors during the day/Florida sun, and no way to adjust brightness; but the reasons I had for buying this particular, less expensive option was for the medical benefits not necessarily the “smart” options, such as messaging/calls etc. I’ve had it 3 days & messages still won’t sync as well as a myriad of other things, but I reiterate, that wasn’t my objective.Great option from medical aspect, as well as look, feel & price!!I purchased this fitness tracker watch to help me monitor my health better. My favorite feature was the bp monitor and that the fitness tracker watch is nice looking. There are some pros and cons to this tracker:ProsElegant lookingIncludes link remover toolMonitors sleepMonitors bpMonitors stepsAffordableFast chargingExcellent battery lifeConsTouch screen isn't as sensitive as it should be, I sometimes have to twist my wrist several times to get it to come on, then, I have to twist my wrist again in order to check readings. Truthfully, it's easier to go to the app on my phone to read the information!I am pretty tech-savvy and it's still challenging to learn due to a lack of in-depth instructions. I had to spend a few days learning how to change some settings on the unit itself.The included instructions didn't state how to change the main screen and I learned that if I hard press on the lower left and hold for six seconds I can choose my display screen.The app is only rated 2.9I wish it allowed for a few more customizations to the unit itself such as the ability to change the screen settings and the ability to set alerts to a custom tone.It would be nice the screen would stay lit for longer than a few seconds when I turn my wrist to look at the time and displays.It states in the included instructions that it will take my bp every 30 minutes, however, somehow the setting changed and at present, I can only take my bp if I use the app on my phone. This is annoying as I don't always have my phone in my pocket.It's difficult to open the charger when the phone is fully charged. It is very frustrating and annoying that it doesn't simply click open when I press the open button. Maybe this will loosen with time and be better, I'm not sure.All in all I'm okay with the tracker but I think that technology could be improved as well as the sensitivity of the touch screen. I understand that purchasing a new unit does have a learning curve, however, this could be vastly improved if the instructions were a bit more detailed and in depth.The style is good. Liked the watch but the spring bars broke off the band. Contacted company trying to get new spring bars and they suggested I buy a new band. Not what I was hoping for. Too bad because I really liked the watch. Not spending $21 when I shouldn't have to.The app glitches. Some days the steps aren't counted. The watch dies after 12 hours. Watches like this you expect 24-48 hours before they die..... nope.App wouldn't allow me to give SMS permission so want able to get messages on itReplacement for one my wife went swimming with, are water resistant but not water proof, charger latch broke. Lucky still had old one for the one she went swimming withI am a avid Amazon shopper. I have purchased several blood pressure watches from the site. I want to tell you that this is my favorite. The readings are very close to accurate. Many people stated they were not. To get more accurate readings you must do the manual calibration in the settings of the app that you download (this is where you would put your normal reading mines without my natural remedies is 130/90). Please note all of these watches are mostly made in China. Therefore you are not going to get the detailed instructions that American products provide. However, the watch is not that complex. It is touch screen and you just simply touch it to change between screens. You should also know this does not take a USB charger. It has a special charger. The battery life is about 3 days if you don't have it set to read your heart rate hourly. If you have the app to read the heart rate every hour the battery will only last a day. I needed to have chargers in several places so I asked a question to the seller, who got back to me right away. They told me to search Amazon under the name H8 Watch Charger Cable to order a second charger. This watch is stylish, light weight, and meets my needs as a first grade teacher who needs to check her pressure on the go.The battery seems not to last long some watches last 3-4 days this watch last a day. Don’t always track sleep and blood pressure.Lovely watch waited along time for it coming trying to find instructions for shortening strap not on instructionsFirst of all, I want to say that it is a very pretty watch. I had a lot of compliments on it. However, the instructions are very poor and it wasn't easy to set up. I accepted that the Blood Pressure monitor and Heart Rate Monitor wouldn't be accurate, however, they are not even in the ball park. I even tried resetting the device several time to see if I could get it to read a little more accurately, but to no avail. Also, I wanted the large number face for time. The stupid thing kept changing the display so that everytime I went to look at the time, I had to manual put it back to what I wanted.Was pleasantly surprised. It is pretty, easy to size yourself with tools provided. Does everything it says it does. Only disappointment is if out of range of phone when you return to range it doesn't let you know you missed a notification.Sleep, really tells you how long you have been in bed. Not quality.Easy to use. Beautiful
