Flip Premium Alarm Clock. Is the alarm really on? Any uncertainty vanishes with this clock from the hands of Jeremy & Adrian Wright for the brand Lexon. Because whether or not the clock sounds its alarm the next morning depends on which side you place the metal case: A tangibly perforated "On/Off" inscription on the top visible in each case leaves no room for doubt. The display rotates 180° as if by magic and also shows the alarm time in the corner when "On" is selected - it doesn't get any clearer than that, good night. And if you want to read the time at night, just snap your fingers - and a sensor for sounds causes the display light to come on. Lexon now supplies the Flip Premium alarm clock with an integrated battery that takes three hours to charge with the included USB-C cable, but promises three months of wireless use.
