Manufacturers of products that have survived my abuse:
Super-T Manufacturing (RIP): Super-T will always have a special place in my heart.
Svomesto: Love the Prime, getting acquainted with the X.
Dicodes: Best balance of aesthetics, functionality, durability, quality, and reliability, imo. I have 3 of their devices. Dropped 2 of them countless times...
Aspire: My favorite mass production company. Their Nautilus coils are my favorite pre-made and they've continued to make them without fail. I very much enjoy the aesthetics and functionality of the Nautilus GT and GT Mini tanks with PSU tank upgrades (4.2ml and 3.5ml, respectively). The Mixx was great as well. Though I wouldn't really buy them, I really like the looks of many of their products over those of other manufacturers. I wonder how Smok won out over them in the US market.
Distributors I currently use:
Creme De Vape: Always been incredibly reliable. I'm a loyal customer.
Nude Nicotine: Been using their nicotine for a long time now.
Bull City Flavors: Just got into DIY. Been using unflavored for most of my 10-11 total years of vaping.
VaporDNA: Good selection and prices
HealthCabin: 3 total orders. Takes only about 2 weeks to get to my door.
3FVape: Waiting on my first order. No opinion yet.
