Glad you are sticking with it Joie and yes there are alot of vendors out there, however it is all trial and error do to taste being subjective. My advice to you is buy in small quantities until you find what is to your liking. I have tried both of the vendors you are referring to and I am not...
Don't feel bad a lot of us feel this way. The bright side is now that you have it there is really no reason to ever purchase another mod. I am slowly but surely just trying to pay forward all of my other mods and accessories to newer vapers :)
I have to agree lately I have gotten more and more poor quality smok tech cartos. I perfer them over boge myself just because they hold more liquid.
What attys are you using that are so awesome that you don't use cartos?
If it works for you keep using it do let others talk you out of it!
