Have been finding the regular 3 button controls on the vv mods a little tricky to get around, then i got the KSD KMAX Holy shite!!! only 1 button to get around all the functions, by the time you click it turns to something else, then when you pause to catch up on whats going on it clears, i can't or don't even know how to read battery voltage...this one button control is too much. and yes i also find setting digital watches a pain in the ass!!!!
