it's probably still a kanger device, even if it doesn't say it or is branded that way, those are the only ones I have seen with the flat buttons, and even as a knock off, it's still a great price, particularly if you're just starting and don't want to invest $ 50 - $ 500 on any given device. Just about anyone can spent $10 or $12 just to give it a try (in some parts of the country, that's equal or less than buying cigarettes)
