It does use an authentic DNA200 board.

Whether it's worth it or not is for you to decide. Personally, I don't really like it because it uses 3 x 18650 side by side which makes it 90mm wide (reminds me of the mod called BIG). It's also on the heavy side if those specs are correct (with 3 x 18650's it's really going to be a brick

)I don't really care for the looks either (personal preference). It seems to me that you can get a DNA250 for a better price but I don't think it's a ripoff by any means (price-wise).
