Well, that's pretty much what I thought about all my starter kits that cost me around $100. These are coming straight out of China, so no mark up, similar to the cartos and m4x models that get fancy graphics painted on them and LEDs stuck into the PCC then sold off for $100 a pop. Quality and performance is probably worth the money, but I wouldn't bank on it being a go to unit, just a test run. Just trying to help folks get in, who are too leery of dropping 30 to 50 bucks on a 510.
The only downside is there may be customs issues in the US at this point, so don't go trying to start a business with a box of 100, or I bet they hold onto it for you. And, you probably won't get any kind of customer service like you would from a sponsor here. For the cost of a couple packs of smokes, it's worth a shot IMO, wish I'da known about them before I bought my first kits.
