Yeah there appears to be a number where the authenticity sticker is. There is a clone version about now too unfortunately, so if it doesn't have a sticker or the copper insulator it's a fake. I know a few poeple that have bought them and they haven't had any issues. I'm guessing the chip is located close to the base, it only gets warn if you are using the setting where the LED is constantly on. Doesn't get warn at all when the you use is in breathing mode or without the lights. It's dropped in price now a bit I think at over $100 it was a bit expensive but I've seen them for about $65 now. It's a fun mod to play with!
