If you use any kind of "standard" carto length tank setup (you know-old school before all the dct fancypants tanks), this is just what the Dr. ordered. Great Boge vape, without all the hassle of cutting/punching them. Same price as the standard ones-awesome. One note-you can flood them if you draw TOO hard trying to prime the filler; perhaps the two-holers (smaller punch) might be better. If you vape high vg, this easy flow would definitely keep it wet.
