From all the other alarm clocks we mentioned this is the best one if you really want to wake up. Why?
Because the Sonic Bomb has a very loud alarm sound that can go up to 113dB, which is the same thing as a loud car horn if you are nearby, is this loud enough to get you out of bed? If not, there is still another device that comes with the Sonic Bomb and will certainly work – the 12V bed shaker.
It works with a 110volt power supply or a normal 220volt transformer, in case the power goes off the alarm will make use of the backup battery. For only $42 you will never arrive late at important meetings, is this a good price?
