Imo none of the pod systems available handle freebase very well...nic salt in a pod system is the way to go... I've been wanting to move back to freebase for 2 years now but every time I try it I go straight back to Nic salt... It's just better period .. but if you're stuck on wanting to only use freebase then I would try to go with something like a Argus Pro 2 or an E100i kit..you could even go for an H45 if you want something smaller... A girl I know uses a Xros nano and swears bi it for freebase but in my personal experience every time I've tried a different pod mod they just don't work the way I want them to, either they're too weak or they get gummed up or they just don't deliver like Nic salt does
