I know a couple like vaporfi,viper-vaper vapeauthority and vaperoyalty
I have a complete setup with Vaporfi, one mod, three tanks and a bunch of atomizers.
It cost me well over 400$ and i'm not in a better position than people who paid half of that.
It seems like quality to me, but I have never tried anything else so I don't feel like my opinion is valid, much.
Their ejuices on the other hand were not disappointing.
You can order them with different flavor strength, I personally liked the 3xGummyBear, 3xApple and 3xRaspberry. Apple and raspberry tastes incredibly strong, almost on the chemical side which is fine.
I've been vaping a lot of tasteless ejuices recently, something that hits you like a truck is very welcome imo.
I'm also Canadian so i've tried "Evaperated" ejuices and loved them.
Bluchie was my favorite, although I was not disappointed with any of their ejuices.
I don't feel like shaming vendors so I won't express my concerns for the ones I didn't like
and anyhow they're all Canadian vendors!
But let's just say that many vendors had low taste ejuices that completely lost their taste after 2 weeks.
Also, beware of high VG juices, they don't carry the flavor very well.
A lot of the most delicious ejuices i've had were pure VG but it's almost frustrating to have that fantastic taste/smell and barely be able to taste it when vaped!
If you enjoy high VG juices, maybe a dripper would be better.
Hopefully more experienced vapers than I could validate my opinion.
