I don't get anything but bud so can only really answer the second part of the question . I don't know of any truly pen size vapes that work well or at all with Bud . I really like the TVape Its quickly becoming one of my favorites But it is the size of a long magic marker and not a pen . There is the Zenpen that looks cool but isn't out yet and may be a long time coming . There are some like the CERA that will do both and don't look much bigger then a penvape also the Inhalator . I don't have experience with either but know a lot of people on the forum like 'em a lot . welcome to the fun !
