I love, try and use Smart-Watches since more than 10 Years. There must be over 90 or more in my Hands. The rugged TANK is a real good one, coming up as M2, T2 and now as X1. All Watches have the same Features : the Standards as Pulse, Steps etc. plus Bloodpressure and Bloodoxygen. Especially those Data are important for People with Health Issues (like me). So I can tell my Doctor what's going on Day by Day or call him, if any Problems show up.
The only "weak" Point is the APP ... It is not actual "State of Art" :
# Data will NOT be saved by switchig from one Watch to another ! This must be fixed first.
# Data can not be syncronised with Google Fit. Many other Apps do this right now.
~ Watchfaces are very Popular, but you can not delete the Build-In (for new WF) and there is just 1 WF possible to add.
~ Europeans prefer WF with clear Data like Date, Weather etc. without the asian Style of colorful Pictures. Just give us "more" :)
