this replace the clock radio we have have since the 90 's . we never listen or wake up to music because my husband need a `` bomb '' to get he out of bed . for some reason , he hear the `` click '' which be very faint , and it start ... very low at first , increase in volume if he do not turn it off . the dual alarm be great and easy to set and the display go from very bright to faint or even off with a push of a button . since the light bother I at night , I turn it off but if need , just a touch of the snooze button show the time for a few seconds . we test the clock when we first get it to make sure it be loud enough to wake he and it be more than sufficient , even though he hear it earlier .
