At home I'll have at least 4 setups on the go, today is -
Uwell Nunchaku/Reload MTL RTA/Blue Razz 20mg Salt
Mechlyfe Ratel XS Kit/3mg Bubblegum
Aspire Deco/GT4 RTA/3mg Berry Burst
Voopoo Drag/Advken Manta RTA/3mg Pink Lemonade
Rockvape Titan 21700 Mech/Goon 25/3mg Blacktunes
Complyfe HK 20700 Mech/Phobia RDA/3mg Lemon Sherbet
Geekvape Mech Pro/Bonza RDA/3mg Strawberry Jam
My current outdoor setups are-
Aegis Solo/KF Lite Plus/20mg Rainbow Soda Salts
Aspire Typhon 100/Ether RTA/6mg Black n Grape
I tend to use a mod for a week then put it back into rotation, I'll use the same tank and juice until the bottle is empty - normally the tank goes back on the shelf, maybe I'll pick out another to use with a different juice at this time.
The only thing that has been constant for the last 18 months is one of my outdoor setups have been the Aegis Solo and a KF lite.
I haven't yet found an all day vape, I like variety
