Initially I was so worried about giving people 510-T kits because they were not very enjoyable, but after vaping all day on a 510-T with the XL cartridges I have to say that I was very satisfied and now I'm confident that everyone else will appreciate these.
It's one of the industry's best kept secrets that 510-T tanks vape like a champ with the XL cartridges so keep that under your hat Phil and don't go speading it around eh.
