i really don't see how these are fetching the prices on ebay. Do people really jump on a bandwagon without checking?

I bought 4 about before the main BL hardware to test my calculations without wasting money and now they're nearly heading towards being 4x what i paid so bang goes picking up a few more just to fill the usb hub, lol

Should really sell mine but it's not to keep your starter equipment as a souvenir.
