Sketchness, reading reviews, posts, etc. I got the impression that ECX was well rated. At 1 liter/100mg Nic ($32) for them and Nude Nic was $105. That is about $70 in difference. !!
I will look at Vapor Tek. I know the Carolina one is highly rated, but also costly.
MFS has a sale and it's just a step below the others mentioned , Vaporstek is your best bet , $25.00 for 1 liter of throat hit , can't beat it .
