SonicAlert SB300SS Extra Loud Vibrating Alarm Clock With Big Display



The SB300ss is a straight-forward alarm clock – it does what it says on the label – and is a popular sale. The display on the SB300ss is one of the biggest (1.8”), and this has a 5-level dimmer function too. The SB300ss is solid and reliable, with a very loud sound. It also comes with a ‘Super Shaker,’ which will vibrate at the same time as the alarm sounding – or, if you don’t wish to wake others, you can set the SB300ss in vibrate only mode.

If you like the look of this clock but have a need for an alarm clock that can be sent with two different alarm times, please check out the SB375ss.
