BYTTRON Bluetooth Smartwatch, Full Round Touchscreen IP68 Waterproof Sports Watches with Heart Rate Sleep Activity Trackers Step Counter Stopwatch SMS Call Notification for iOS Android

After a week's use, I really love this smart watch. It looks stylish and easy to connect with my phone. Very comfortable to wear it. It has numerous sports modes as well as all the usual smart watch things like heart rate, steps counter, blood pressure monitor and etc. it is a really great watch with a decent price. I will recommend it to my friends.

Watch is pretty good badly let down by some absolutely amateurish software which loses connection, then fails to connect or find your device even though the phone can see it quite happily, randomly stops recording and just tells you you had no heartbeat or blood pressure for the last 10 hours.The software is terrible: it does not follow the development standards, refuses to shut down even if you force stop it will just start up again, takes over your device, wants to stop your blue tooth service because the devs were too lazy to refresh the screen, etc., etc.Updated 15th April 2020: Now the watch has decided I have no heartbeat! Watch is almost as bad quality as the absolutely useless software

This may not be name brand but it's a watch that does a lot more than tell time.The screen is clear and bright and looks nice. You have a few options to change out the face background if you want the watch to look different.The battery lasts about a week for me on a 4 hour charge. That's pretty darn good. Unlike a fitbit that just tracks steps and heartrate, you can track many other neat stats with this. It has countdown and stopwatch features that I haven't used but I have used the blood pressure monitor and it seems pretty accurate. You get the usual heart rate, sleep monitoring, steps and distance with this as well.If you have super large wrists the band maybe too small for you. Usually when I get something that's a once size fits all wrist band, ie the bands from disney world, they either barely fit or dont fit at all. This smart watch I'd say is a little bigger than the usual suspects.The device has a proprietary charger that you would need to be sure you could keep track of and not lose. Its highly magnetic so it stays in place while charging. It's also a bit short. Mentally account for that when you're thinking of your charging location.Overall, nice quality feeling smart watch that works very well so far. Oh and its waterproof so feel free to shower with it or wash it in the sink.

I had to return the watch as it uses the H Band App which is very poor and keeps disconnecting so increasingly frustrating to use.I wish that Amazon would look into all these watches that use the H Band App, it's poor and the developer does not respond.Even though the watch might be good, I wouldn't recommend any watch that uses the H Band App so please look at this before purchasing.

A nice looking smart watch and very comfortable to wear. It has a good range of features. Id question its accuracy though.. i done 7km on threadmill this morning and its only registered 4.2km so that's a big discrepancy. The app that partners this phone unfortunately doesn't seem to have a function where you can input manually to correct this so it seems my exercise information is going to be incorrect daily which defeats the purpose of wearing a smart device.

Took several attempts to connect to this watch. Then when it was connected it would drop off again shorlty after making the notifications useless. The heart rate and bloodpressure monitor on this watch is way off so don't buy it if you wanted this for health reasons. The watch its self is quite nice but the charger was rubbish.

Bought this as a birthday present to my brother and it looks good on him. This is the first smartwatch he have he is not that techy so he prefers just ordinary watch but because its his birthday I bought this for him to level up his watch. He loves collecting watch and he loves it he can monitor his health and connect his phone to his watch. Easy to pair.Recommended

This watch is a nightmare,its the hardest thing to ever understand and pair with your bluetooth,I have been trying all night and most of this morning and still don't seem to be getting anywhere with it..The instructions are so difficult to read and understand smallest of print.There is no online support anywhere ..Nice look watch,heavy to where which I liked,but apart from that useless..Overall don't buy .poor instructions and no support.
