I have a Bonza (with all the spare parts, box, etc) I could trade for your DR but mine (all of them?) has the issue with the negative post coming loose that I have seen others complain about. If you don't care about that issue (the spare parts bag has a spare screw I think, or you could loc-tite it?) feel free to shoot me a PM and we can swap addresses. I will even ship mine first and let you test it before you ship yours as I will not be vaping this or ever buying another Bonza or
@Vandyvapor RDA without a milled negative post/block.
