There are selections that pop up on the screen that aren't mentioned in the user manual. Instructions are manageable but not worth going through that many steps to realize you can't change the a. The time is hard to read.

As soon as it goes off in the mornings, i'm awake instantly and i use the snooze button a few times until i'm sick of all the bed shaking going in lol. It def wakes me up.

Is removable/unpluggable and the cable is a good length. The vibration is gentle.

With the plethora of options, sleek look, and option to have physical feedback with the bed shaker, this one is worth your money. Only complaint is the batteries.

Easy to set up, brightness is adjustable, loudness is too. Display is nice and big but could be a little brighter.

This thing isnt even louder than my phones alarm, and my phone really *! It shakes nothing. I'm a very heavy sleeper so it's hard to wake up to just sound alone.
