The vibration wakes me up just fine. The beeping isn't loud, but will wake most people. I love that this clock allows me to infinitely hit the snooze button.

It works exceptionally well place on a hard surface or worn under clothing. Keep the device hooked to your pajamas. Clip it to a pillowcase or wherever you set it.

Great compact, lightweight alarm for travel. The feel is solid and not flimsy. Easy to use, lightweight.

The noise of the * on a hard surface is very loud. Heavy vibration just enough to wake this deaf sleeper. The shaker is only good if it is close enough to you and i mean close.

This clock is completely unreliable. One day it works, the next it does not. After some time it just wears down and isn't as powerful. Sadly, it works maybe one day out of four or five and that is not what you get an alarm clock for.

The hinge for the display panel feels much cheaper, the color of the test button is mismatched. The device's round shape and odd button placement make it a pain to use.
