Very nifty idea!!
Bought it because it sounded "COOL" !!! LOL  I actually really like it. About the size of a standard lighter but doesn't weigh as much. Seems to last at least a few days worth of lights without needing a recharge and it is extremely convenient. When I sit down at my computer, I just plug it in and let it recharge for a while. Just a note, the box it comes in is tiny so when your shipment arrives, if it is packed with any other items, you might think it wasn't included in the shipment. I didn't till I went through the package again for that reason.
