    Sigelei fuchai duo 3

    I bought this mod during the black Friday sale. I used it less than 2 weeks before it started auto firing on me. It was never dropped or abused yet failed almost immediately. Don't waste your hard earned money.

    Fuchai duo

    Sleek and clean design. And the screen is amazing with color. Power seems true, however, the only complaint I have is the fire button. It is really click, but seems to fire every time I put it down on the button side. And especially when in my pocket. Wished they'd made it a little more difficult to fire? But still love it
