  1. Nick Soule

    Feels solid in hand, has some weight to it. Easy to use and wattage is very accurate.
    unstable on the table…

  2. Domi

    The mod is very good. steel and heavy for such a compact size. he comfortably holds in his hand and the fire button is under your finger. The mod is controlled not by the up and down buttons but by the joystick. You can manage the settings from your smartphone through the app. cool mod on a fail-safe board.
