first let I say I only write review if something be really worth the time or it be so horrible I would hate to see anyone else waste they money . this alarm clock be absolutely wonderful . my oldest daughter absolutely hate get up in the morning , and try to get she up be no picnic . we try other alarm clock , but they often shut off after a certain amount of time or be not loud enough -lrb- read : she sleep right through they -rrb- . not this one . we have it on a low volume and it be still loud enough to spring she out of bed and into the bathroom each morning . -lrb- my husband be outside one morning and could hear it go off ; I have be all over the house and have hear it go off -rrb- . it sound a little like a fire siren . another nice feature be that it automatically reset itself for the next morning when you turn it off . no have to remember to set it each night . we have have this for several week now and it have really improve we morning . the cost seem a little high ... but if you have a kid to get up in the morning who will not get up , this price be absolutely worth it .
