$40 with just a USB cable to charge from a computer port, or $50 with the wall charger. I thought I ordered the one with just a USB cable, but there's a charger in the box, so maybe I got the wrong SKU when I was placing my order. Anyway, for something up in the DiNotte intensity range, at a price just a little higher than some AAA-powered blinkies, it appears to be a good value as long as it proves reliable, which will take some time to establish.
