Guys, would like to know your opinion on these 3 tanks - TFV4 mini, Bellus & Crius.

Which one is the best in terms of flavor, ease of use(filling, rebuilding), resistant to leaking etc.
Any pros/cons you can list down?

Are they usable with 70/30 or 80/20 juices?

Currently using Sigelei 75W and subteng.

Im only speaking for bellus. Flavor is good on dual coil. If single its normal.
However for bellus it takes practice to wick it right else it will leak like a bitch. And u know most ppl like to exhale before inhale when firing? Dom do that on bellus.....

I saw someone said crius is so e sor idiot proof, migh get one to test on idiot like myself....wating for shopee for v3 lul

Bellus does the same too 
I only use rba head, never use occ one lol.

And bellus cheaper N smaller. Tfv4 too big unless go mini. Crius or crown is my next

IMO comparing the flavor and clouds of the single coil RBA to the dual coil RBA, the savings on juice and batt is not something you'll readily want to do...it's too delicious and the vapor's thick and rich

It's only RM65.80 including poslaju after 30% discount at Shopee, Joenida's shop and the dual coil RBA is an additional purchase. Hardly a big risk eh?

Some minor cons:
Please note that the thin translucent silicon o-ring at the bottom of the RBA/stock coils is not hardy and wears down/gets torn up easily. Even Rip Trippers scolded Smok for that poor quality o-ring! I've replaced them with a tougher quality one that's 0.5mm thicker, easily obtainable cheap cheap from any bearing and seal shop. One more downside is that the wicking may be a bit hard if u r a beginner. But once u get it right, the rewards are worth the effort.
