I haven't used the snow wolf yet but according from what I have seen it passes the cotton test pretty well.
the biggest issue is the lack of ohm lock. Sometimes the mod doesn't change from wattage to TC quick enough and it messes up the readings.
Ofcourse you have the newer snow wolf asmodus edition and that has a ohm lock function and manual mode selection.
also this is how I ended up doing the + and - buttons(mostly because we couldn't figure out how to make them work with the chip sled in the way)
I kinda like it. Since now you don't have to move your thumb around to reach for the + and -. just use the rest of your fingers. like this.
and yes I messed up while building it and picked the wrong side to put everything so the battery door is now always facing outwards of my hand. Eh I don't mind. this is meant for performance damnit and not looks.
