Those of you who are married will certainly have encountered times when your alarm clock woke your significant other and that resulted in them going around with a bad mood for the rest of the day. Well, the Shake n Wake Silent Alarm Clock aims to help you tackle that problem. It’s a silent and wearable alarm clock that you wear like a watch, and it’ll vibrate when it’s time to wake up, simple as that. It’s currently going for £14.99 ($25). As a side note, it would also be quite useful for those of you with hearing problems.
