At first it is quite confusing as the hour set button (shown on the left of the screen) is precisely the one on the far right and the left button sets the minutes displayed right on the screen. But we quickly get used to this reversal.
I did not find any difference between the two ring styles (normal and snooze).
Permanently stop the ringing by marking the corresponding button and dragging it to its proper place wakes you up completely.
In summary, a small alarm clock, pleasant to use and effective.
And solid: I did several times drop test on different soil types and at different heights, and it still works perfectly, without even a scratch.
For cons, the foot comes off too easily if it strength, and refitting is tricky.
Complement after 2 1/2 years of use:
I left almost 1 year in a drawer without serving me and I thought I should replace the batteries. But no, always on time to the minute and still brave ringtone.
