I like least:
- The extreme lightness of the device (I do not know you, but I wake up, I'm clumsy ...)
- Little intuitive side settings (this is the first time that I need to look at the manual alarm clock !!)
- The fact that the bulb can not be replaced. At its maximum setting, light enough to read ... but how this use-it reduces the lifetime of this revival almost 90 euros?
- The astonishing lack of a battery saving time in case of power failure !!!! I did not know that there were still revivals that have not this safe! A failure of a few seconds is sufficient to put the time at 0:00 !!!!!
