I have a Greenlight branded version of these devices. I took a chance buying these blue ones because the pictures looked exactly the same and the price was much better. The only difference I can see apart from the different colored LED is that the branded version had a reversible USB end of the cable whereas they have the traditional key to insert the USB connectors one way. That's not a problem, because after connecting the USB plug, it remains for my applications, and its reliability and quality is still identical to the more expensive version. So save your money and buy one if you really don't like the ease of a reversible USB connector.
