before i write this i need to acknowledge that some of these units have had issues with the fire button.
with that said try to think of one company that has not had one unit not have an issue?.... you cannot and trust me i've bought smok products. not something i recommend anyone doing.
just know this could happen and understand the return policy from where you buy this or any product.. as for myself i trust Eciggity to make things right in this event.
now as for the voopoo drag?
very solid unit and yes the battery door will rattle if you move it. otherwise mine seems solid and does not rattle on normal use.
it is a box, is not the most comfortable unit to hold for long but is not the worst either.
i use mine mainly at home so not an issue for me.
it is very well built and has some weight to it as well.
this is by far the fastest hitting mod i have ever seen hands down. firmware can be upgraded and has plenty of power,
this has become my go to mod over the last cpl months.
would i buy it again? yes and i think you should too
