Hi all vets out there in ECF!! Need a quick check of quality for those made in ROC mods. Are those clones or OEMs? Anyone with information pls help! I know that a lot of PVs out there are ROC products.
TIA!~!
TIA!~!

your question is very wide.
which PV are u refering to?
there are many from us, france, german and china.
anyway mostly are clones.
for natural -> the firing button is none repairable.
zmax -> get Segelei oled version will be better
kts -> if u don't want any of the function like in e zmax.
china product is up ur luck, china qc is so-so only. u may get a dead of out box or a prefect working ones.
Ya lor... My 4D luck have never been good haha haha.. The segelei moq is 10 piece wor... Ooops
Hmm i tot pravari is from ROC?? natural does look sleek..
Republic of Congo makes mods?!! I must be having a nic OD...
Anyway, chris made a few good points and a few off-ish ones.
In what way(s) are e Vamos and evics btr than e Zmax-es? Here's a look-see...
1) Vamo in 18650 has a 3 amp limit; stacked 350 @ 5 amps. And... it tops at abt 13.5W typically. Cheaper than e other two and looks e bit.
2) evic has a 2.5 amp limit; 5V max and typically tops @ 11+W. Options are only good for fussy puff-counters. Good point of this is that you can buy replacement control heads and tube.
3) Zmax has a 5 amp limit; and it tops @ god knows how many watts as e output is rather inaccurate. Cheaper than an evic in most places.
So... it's quite a coin toss situation here.
