I've tried it with RAW's, Daysavers, Zig-Zags, and Blazy Susan cones. Works well. Fill your pre-rolled cones and tubes in seconds with the push of a button. Take your Perfect Pack anywhere; USB-C Plug-In or battery mode (4 AAA batteries). The USB-C adaptor allows you to run your Perfect Pack 2 directly from your phone’s battery. Choose your density and fill evenly from filter to tip with your choice of flower. - Fully Portable Joint-Filling Machine - Push-button pre-roll filling - Fills from filter to tip - Adjustable density knob - Pairs perfectly with Artisan Tubes The DaySavers Perfect Pack works best with 84mm half-gram pre-rolled cones, but larger sizes can be accommodated as well. Just insert the pre-rolled cones as far as they will sit on the barrel and fill as normal. You may need to maneuver the cone around as it gets toward the top, to ensure it is filled perfectly.
