this little clock only measure 2 '' x 2 '' but it be simplicity make up for the tiny size . the off\/off button be simple to operate -lrb- up for `` on , '' and down for `` off '' -rrb- , the time and alarm be easy to set , and the clock make no noticeable tick sound . the alarm be reasonably loud . I would have like something larger and a bit more robust -lrb- I fumble in the morning -rrb- and be amaze at how difficult it be to find a simple battery operate alarm clock that do nothing but keep the time and wake you up .
