get the uwell crown if you wana do 30-50w
get the freemax starre v2 with ni200 if you wana do temp control 30-50J
get the tfv4 with quad coils if you wana do 80w+ vaping AND you DIY
all three are good options... except the third will probably kill your batteries like crazy... i already do 3 pairs of 18650s a day... imagine i get the tfv4... i might need 4-5 pairs lol
I have the FreeMax Starre Pro and an Arctic tank.. I vape around 40W so I'm looking at the Uwell Crown tank hard... also have a Subtank Mini but it gets no use...
