Edit: Drozd, that's funny we came up with the same three with all the people selling them
Lol those are the 3 I've dealt with the most and like dealing with (well janty now for the eGo)..and the hardware has been dependable..
and those 3...well cignot is $35 for the kit and like $5 for shipping and you gotta add juice..sell out alot and sometimes have limited color options..
RMV is like $44-$46 again gotta add juice but has free shipping..and has more color options
Nhaler with the coupon code just a starter kit is $49.30 shipped and has those 2 6ml sampler bottles of your choice of juice..so right off the bat you can do 12mg strength (HV juice) the 18 mg the kit comes with and 24mg..and usually has quite a few color options..
And darn it I like options at a decent price all from one place..
EDIT: and I get equal shipping time from all 3..
