Aye, Basium is really short for an 18650 mod, personally, being a large handed fella, I'd have preferred the Basium to be taller but I got a comfy fit tucking my pinkie under the base
Basium and Rage are both 8+ months old mods, an eternity in vaping - Topside is very new and you pay for the capacity improvement in the height of the mod. But all are very decent mid range dual battery squonkers - buy what you like and can afford, you'll not be disappointed with any of them
I'd still like an original Topside 21700 - ordered one cheap in the sales that got cancelled, bought a super cheap alternative that arrived not functioning as it should do
Got a nice atty I plan to to run at 65w ish max and think a single 21700 mod running a Samsung 40t would be a cracking daily carry - I'll pick an OG Topside up for it at some point.
