I would highly recommend purchasing from Sun & Moon Ecolight. I've bought most of my book lights from them (2 Travelflexes, an Xtraflex2 and the Ultrathin book light) and they usually send out my purchases within a day from receiving the order. They also keep me updated with tracking numbers (without me having to ask for them). Sometimes their prices are higher by a dollar or two, but they offer free shipping so it's still worth it
