I’m a busy tradesman and work long hours which means late night & early mornings and I have been known to sleep through many alarms. The sonic boom vibrating plate is really effective & u can set 2 alarms & also set it to either both vibrate & alarm & you can also set the alarm sounder tone pitch. Or u can have just the vibrate or just the alarm tone. Very good product. Impressed me and works a treat. If set too loud though u can wake up in a panic and smash the alarm straight off & straight back into a deep sleep......oops. So be warned set the tone accordingly.
This is just what I needed being such a heavy sleeper. The alarm and shaker pad on this clock would wake even the deepest sleeper! I can't recommend it enough! +++++ The instructions are clear but it does takes a while to figure it all out, but when you do it is worth it. Worth every penny I paid!
Excellent seems expensive but when you need some method to wake a teenager when they have to get themselves up. Pleased to say it worked well and wakes him immediately and is switched off because it us so loud but not frightening like all those bell style clocks.
