Are these gone for good? They were what I would suggest to new vapers and buy for family members. I noticed there are now Riva-T kits, but I really think atty/tank cartridge combos are inferior and can't recommend them to people. Perhaps it's been awhile since I tried it, but I tend to steer people away from those and eGo-C's. Also, if I were to tell someone to order Riva batteries (out of the kit), do they still use the EM cones or must they order the Smoktech eGo cones?
