They are not supposed to be liked but to speed up the process of getting up.
You should know they are very LOUD, extremely ANNOYING and HARDcore. So it means they are bad for YOUR ears - REALLY.
They may not help if you go to sleep too late because probably nothing can make you up if you are too sleepy and too tired - you are just a human being. So before you decide which one to use make sure you will be able to get up anyhow.
WHILE WAITING FOR YOUR DELIVERY - PLEASE BE PATIENT - THANK YOU
I hope you will like it!
