If you are the type that always plasters Post-its all over your house and then forgets about them, the Memo Motion Sensor has been designed for you. When you enter a room, it immediately starts playing back a pre-recorded 10 second message. With dimensions of 7.9 x 4.7 x 10 cm, it comes in its own tray, runs on 4 AA batteries (not included,) and carries a MSRP of 19,90 € (~$27.00.) There’s only one problem. If that message is to remind you to feed your cat, and the feline beats you into the room, will she/he know enough to open the Fancy Feast?
