arVin Smart Fitness Tracker Bracelet, Bluetooth V4.0 Intelligent Step Tracker Calories Tracking Health Sleep Monitoring Call ID Reminder Wrist Bands Wristwatch (Black 3#)

Bought this for my husband as he n eds to monitor his heart rate and blood pressure. It is a nice watch however, syncing with the android app is a nightmare on his phone which we are now sure is because the memory is too small (8 gb) so currently the app is installed on my phone.It does what it says and on the box and charge lasts. For some reason we received two chargers.Not sure it is recording steps correctly. I have a different band and this Arvin one records a lot higher step count than mine.My 4 rating is because of the syncing issue I contacted Arvin support as advised in the box but they haven't responded.

My biggest complaint of this device is that the battery live is terrible. With a full charge the device only last about 6 hours and this is without constant heart rate monitoring.It doesn't seem to automatically sync and record the data on the mobile device and all the data is lost when the device loses power.Wish i hadn't thrown the box out or i'd return the device.

Your browser does not support HTML5 video.  Brilliant fitness activity tracker, can't believe some of the features it has, the obvious is step tracking but it does sleep, calories oxygen monitor and blood pressure and then so much more.Was very nicely presented in the box, easy to charge. Just download the app Hey Band then using the app simply pair. The App was better than I thought it would be just swipe down to refresh. The instructions that comes with this are very helpful and has a lot of information.It has a nice strap and is comfortable.You can turn screen on by tilting wrist towards you or you can turn that off and just use the button.The battery will last 3-7 days depending on usage.It is compatible with Andriod and iOS so will work with most modern smartphones. I tested the heart rate monitor to an Apple Watch 2 and the results were the same give or take 1 or 2 roughly 80 for me.It's also spashproof. I'm very happy with my purchase and would definitely recommend it.

There doesn't seem to be anything good to say about this item (Fitness Tracker Bracelet). I can't log In to the APP. It keeps telling me that it's not recognising my e-mail, no matter how many times I try. I can't say honestlly that it is value for money. Another thing is that the user guide is such small writing you can't read it even with a magnifying glass. Could have bought better. The one that I've purchased will be going in the rubbish bin after my lesson has been tragically learnt.

The watch is good, but It doesn’t connect to the app, it gets disconnected all the time and it is difficult to keep track. I bought it for my brother, to measure his blood pressure and he couldn’t use it. Also the blood pressure measures are not very accurate and the app ask you to correct the values. The other functions works ok, notification to drink water is very practical.

This worked fine for a couple of days, but suddenly when i went to the app to check my progress it said 'device not connected', it would not connect to the device unless i powered off the app source and then switched it back on, it was working again. However each time since i returned to the app it says not connected. Strange how it worked for a couple of days but not since? Not very reliable.

Excellent fitness tracker, given as a presrnt to my Mum after she lost her previous one. It was easy to set up and pair with her phone, she has been using it to keep track of her activity and heart rate during exercise.She is really pleased with it and finds it comfortable to wear all day. She really likes the look of it and has had nice comments from people about it.

This watch does what is says in does with on BIG problem. This constantly fails to sync, with my android phone. I have checked all the app upgrades and still having the same issue.The nail in the coffin for this device is I tried to change my password, it allows you to change, but then does recognise it. You just see Chinese writing
