I've used a vibrating alarm since our son was born more than 10 years ago. I like that it wakes me up, but let's everyone else sleep. I love the vibration vs. grating, shocking alarm buzzers, bells and whatnots. Much nicer to wake to the vibration.
This clock is small enough to use on our tiny nightstands and is very conventient for travel. Once it goes off I just set it in my hand or under the pillow for a snooze or two. Large LED works if you are near or farsighted which is quite handy as well.
Only complaint: the snooze is at 4 minutes, I'd much prefer 10. yes, I am a snoozer!
