Looks smart, feels good quality
2 days in...Looks smart, feels good quality. Unfortunately the good news stops there.I sent a query through the app to the supplier but got no response.1. The step counter - doesn't. Most of the time it does nothing at all. When it does, it may jump by anything from 13 to 621 steps2. The Sleep function was my main reason for buying. Apparently I had 0h 00m sleep last night. Now, I am a poor sleeper but I'm pretty sure I got at least 2 hours last night.3. Instruction leaflet virtually pointless - no info on how to set the sleep period or, if it is preset, what it is.4. Says to calibrate the blood pressure to another monitor, but no detailed info. I did work it out but as BP changes with every reading on my arm band BP meter, what are you supposed to use as the calibration reading? No info or suggestions on thisGiven point 1 and in particular point 2, I think I will be returning this and looking for FitBit.

Well worth having!
Very good product and accurate as far as I know. Excellent quality including the strap.The Instructions could be a lot clearer, having said tha,t it was quite intuitive to load all of the information and link with the PC/Tablet. However to clear all data and restart meant uninstalling and then reinstalling.

nice design. waste of money
the display was not working well after a day of usage. It was impossible to restart the watch. I liked the design and potential functionality, however, i do not think that i would recommend it to anyone. Item was returned as is faulty.
