Hey whats up guys i just picked up a sigelei 50w vr 2 and its a little different from the reviews ive been seeing......it does not come with a screw driver and also the 510 piece does not stick out of the mod like in the reviews it sits flush with the mod im pretty sure its authentic but i just wanna make sure with u guys also if it matters i got it from 101 vape.....im guessing those were just some updates sigelei but doesnt hurt too make sure
