4 out of 4 Smok mods I've bought this year have been from UK vape sites, so not sure where you get that UK sites won't stock them. All were bought from well known UK vape sites. Also bought the Mdura Pro from a well known UK vape site. All I've bought have been good mods. If they fuck up, then they fuck up, but I honestly think Smok mods are a lot better these days. Just my opinion though
