over the past few months no matter when you ask viofo when they are coming out with the A129 CPL Filters they say 3 to 4 weeks, they just keep saying it, they will be saying it till its 2019 when the A130 dual comes out lol. obviously, they don't want to embarrass themselves to tell us the truth of why its taking so long, they know they just like to hide it for unknown reasons, they already made a batch of them to sell to new customers in a bundle deal, so we know they can make them, they just don't really care, its obvious
