I be currently a 19 year old hard-of-hearing girl , who be also a deep sleeper , and I have have this alarm clock for probably 9-10 year , if not more . no , not the same company . . the same exact alarm clock . it be loud enough for I , and the bed shaker be very effective . maybe it be just I , but after a while , I get use to the sound and do not really hear it anymore when wake up . now , 10 year later , I be finally shop for a new vibrate alarm because now , the time will speed up . . so I 'll set the time correctly at night , and then when I wake up , the clock will say it be about 4 hour later than it really be . I be definitely consider get another of the same product , just because this one have last I so long .
