As you can see, it’s very simple to use this device. Just cut half the lemon and put the face down to the plate and… TAADAA! The digital clock light up! 😉

The only downside is the short power supply. As the lemon dried up over time, the digital clock will shut down. Well, how long do you wish a lemon can last? If you need it to light up the whole month, you’ll need to replace the lemon each week because that’s the limit of every lemon.
