One moves known on a sunny day more than in the rain and in the brightness of the display (as well as all displays, except e-ink display as Amazon Kindle, etc.) poor to barely legible. The display is also not "live", so that one only sees his penultimate values and exactly causes the display ad absurdum, because there I can also buy a tracker without display, which is smaller, more inconspicuous and cheaper plus usually even more can, such as announce by vibration Awakening or alerts and calls. All this can not this fact. But I can also tell time, which I do not mind bringing in the sun. The biggest drawback for me was that the size of the bracelet with inlaid tracker itself for my man's hand is much too bulky and uncomfortable to wear by the Metallschliese at the bottom, because the skewers through the very sharp edge in the skin. On one hand this woman tracker also looks more like an ankle monitor a correctional facility. The corresponding app is designed for pretty, but the transfer of the data of the tracker via Bluetooth takes a relatively long, so you need some patience. Again, the penultimate values are transmitted oddly always. The pity is that you (etc. as blood values, weight) due to the lack of any other devices in the app, can not hide the other unneeded data. It is better if one (so sphygmomanometer, scale) gets displayed only when connecting the respective devices these things would be. Speaking app: The values are entered in the Online Medisana portal and without registration there, the device is not usable. Anyone who is not a fan of information disclosure, this unit can forget it. All in all, the tracker for about 50, - Euro no longer so halfway in order, as well. I gave it back and bought another much cheaper, with which I am really very satisfied even after prolonged testing.
