The alarm clock works well with light. This device is fully touch and it's quite nice to use, the lights of buttons light up as soon as you approach the hand. There is no battery but when I disconnected to move it, it was left on between 1 and 2 seconds so no worries for micro cuts. I had no trouble understanding the operation of the unit. The only regret I have is that the light of the clock, even if it seems small hyper day is still too high at night (I have too enjoy to sleep in complete darkness). The integrated light and super low power function are downright delectable.
