I don't have to deal with the batt/joose issues many of you do... folks still working for a living, always on the go with family or friends, etc. But the Grands & 18650 Woodies still won out around here even though I am home most of the time where batt life/bottle size doesn't really matter at all. Now days I can just load up all 5 Grands, the 2 18650 Woods and one of the Baby or the Mini Wood for my walks and I'm good to go for a day/night plus depending on what else is going on around here. If there's not much going on I can go through 30-35ml of joose a day in the Reos though. With 40 batts... in use, charged or in the chargers I change out batts whenever I notice any drop off in a Reo. Am also running RxW more than cotton in the Reos now days, so not rewicking for weeks/months with each Reo/atty dedicated to a specific joose.
When I bought my first Reos I fell into the "upgrade" things. With a lifetime supply of 3ml/6ml bottles I still bought 24 square 6ml bottles for that mod; with lots of spare springs for all models I still bought something like 25 spade connectors/50 10amp fuses for that mod; also 3 or 4 extra brass doors to patina, etc... none of which I ever got around to. The Reos work exceptionally well just as they come from Reosmods.
My Reos are the easiest vape gear I've ever owned that always give 110% reliably, and with very little muss or fuss. Thanks Rob.
