I use a plastic bag to carry the glass. They gave platic cases you could clean out a cigar tube or something if your worried about the stem breaking. Planetvape.ca I believe had stems with more airflow but it kills battery faster . I wouldn't get the air tho the analog and digital ones work great and are portable. Only thing mflb is great for is stealth palming it everywhere lol. It is a cool invention tho I used to love mine. You
can replace the battery inside the solos there was a guy selling higher powered batteries that fit that has more juice. The battery lasts an hour if you need more vape then that get more batteries or a dab rig
