I've been using my eRoll for about a week and a half so far. During the day I normally vape 808s for convenience of size and dependability. This has not only completely replaced them but cut my mod usage at home and I'm not going to look back. The ability to comfortably vape hands free and still get a decent hit when I'm busy is priceless. The production on such a small
device is amazing to say the least and on the few occasions I have vaped the battery dead it has only taken a short while in the pcc until I could use it again. If anyone is considering buying one I have a couple of suggestions. 1. Up your nic level. I bumped mine up from 18 to 28. Reason being it's not for chain
vaping and when I'm busy I need the most nic. 2 I increased my pg from 50/50 to 60pg/40vg just to get a little more throat hit. I don't think it wuzz necessary though and probably won't do it on my next batch but if throat hit is important to you this helps. 3. Order more cartridges/
tanks. You can't put too much water in a nuclear reactor. I carry a 5 pack in a plastic carto cast plus the one on my device which gives me enough to get back home and fill them all at once. YMMV. I can't comment on atty longevity yet because the original is still performing like new. You can prolly clean them but I don't know how really or how you would dry burn them unless you've got a manual ego c. If it lasts over two weeks I really don't care and will consider it a consumable, probably the same expense as a carto for me. I also wouldn't waste my time or money trying lr. I got one and can't tell any appreciable difference and it's prolly harder on the battery. Don't let the mah throw you. You're leaving home with about 1,090 mah, slightly more than a 1,000mah ego. So far it's been hassle free and except for evenings it is actually becomming my primary device, meaning I use it more than my twists and mods combined.
