The product is functional. The screen on the unit displays the number of steps, calories,% of target. It is visible, simple one button. The switch to night mode is manual. Data is shown on a dedicated site medisana. It is necessary to register and provide some personal information. For cons, the application on Android is unnecessary is best requires a lot of rights to the phone, such as access to such number, address book to name a few, up to you to see Different information is grouped on a home page. The results are displayed in a graph. Sleep is visible via vertical bars on three data (Excellent, Good, Bad) and every 1/2 hour.
The counter seems not function properly.
That said, are succinct information on the site. Is it me waiting for me to analyze, especially for sleeping part? That understand when the graph indicates Bad sleep periods, the number of good sleep? That's probably where I expected something else
Otherwise, the product is absolutely not waterproof, I unfortunately forgot to remove my pants and passed to the machine. Not survive damage.
Oh yes, the fact that it can be worn to handle that sometimes we forget or washed ...
