The high-tech version of the sticky yellow Post-It note, the new Digital Video Memo from Firebox offers a 21st century way to leave a note to your significant other, offspring, housemates or colleagues.

The tiny device (it measures just 5.6 x 5.5 x 1.1cm) has a magnetic back so is fridge or filing-cabinet friendly and can record a 30-second video message.

Charged up by USB and boasting a 1.5-inch OLED display, the gizmo has an LED light that flashes to alert that there's a message recorded and ready to go which will play at the press of a button.

The Digital Video Memo is on sale from Firebox now for £29.99.
