Great quality fitness tracker 👍
Great quality fitness tracker clear screen and a quality strap, very easy to use just download the app, i was surprised how many steps im taking in a day, and how little deep sleep i have. Very happy would recommend.

The time is big and clear and it is easy to tap though the modes
I am impressed with it's stylish look and it does everything I require and more. The time is big and clear and it is easy to tap though the modes. I like the colour display & the functionality, particularly the heart rate and blood pressure. Blood pressure results I cross checked the against the doctors reading and it was exactly the same. Feels nice on your wrist to. Really impress with this. Recommended.

Not 100% Acurate
I bought this to keep an eye on my blood pressure, but it is not very accurate, but OK for a guideline. It is much lower than the arm band machine I also have. The rest is good though, I can see how many hours I have slept and how many steps I have taken in a day, and this appears to be accurate. The only problem I have found it that the battery life is very short and I have to charge is every other day otherwise it runs out.

Worth buying
Colour screen with durable band, I'm happy with it. The pedometer works excellent. IP67 waterproof is very friendly. If it has blood oxygen monitor, I would love it more.
