This is very convenient in many ways:
-on the branch (no need for polluting batteries)
-on can choose the strength of the light signal indicating the hours and minutes: strong, weak or off (no light at night)
-on can plug in for a nap by choosing from 5 minutes to an hour or two.
-on can record two clocks with a memory 1 and 2. This avoids time-consuming manipulations.
-it is possible to choose a ring that breaks the ears and we wake with a start OR RADIO. Only flat, to save the radio mode, it is not obvious, because by default it is connected to the ring mode (I recommend you for a gentle awakening ... If you want to jump in the morning and getting out of left foot, it's a good thing !!!)
-The radio captures very well and we can record the various stations by selecting the volume.
In short, a very satisfactory purchase and practice I hope I will stay a long time ... even if it is not a known brand. The price is also very attractive.
