Not the most earth shattering gadget in the world… but I love mine. For only $4.25 (perfect gift item) you can get a bright 3 LED solar keychain. The keychain is pretty small (2.05 in x 1.34 in x 0.35 in) with a simple design – a solar panel on one side that charges the internal battery, a button to activate the lights, and 3 bright LED’s.
