I get this little guy base on the good review . we use it on a 12-day cruise in the UK in which we be horribly jet-lagged with a 8-hour time difference . the clock be small , lightweight , compact , and incredibly easy to use and set ! I love the giant button which light up the number in neon blue . it be very helpful when check the time in the middle of the night . I love that it blink in red when the alarm go off , and that the snooze button be so large . I highly recommend it !
