Query: Sonic Boom Alarm Clock

I bought this Sonic Boom Alarm Clock to replace the one that wore out. My husband is fairly young and has aprofound hearing loss, so he doesn't hear any alarm except one that vibrates. This particular one works as wellas the one he bought before, which was a step above this one. This particular one is perfectly good thoughbecause he doesn't need any more than the basic sonic vibration. The other one is heavier. This is more lightweight, so its easy if ur traveling. My husband is happy to have this clock, so he doesn't have to worry aboutwaking up on time for work. Im grateful that I don't have to hear a regular alarm go off at 4am in the morning.
