These guys deserve 5 stars in my book due to being the best in the immediate area in my opinion, along with other reasons below (though not the best in Phoenix).
They have very friendly and considerate customer service with fair prices based on popularity of juices it seems. Their selection of juices isn't large but it doesn't need to be, as sometimes that can get hectic. They have one flavor that has become one of my all-day favorites and I've had similar from more popular vendors that don't compare.
In terms of mods/devices, they have a selection that caters to all types of vapers, from beginner on.
The parking can improve, but it is beyond their control. Additionally, there is a tattoo shop in their with an artist that seems to do great work. I will stop by often for my all-day vape and perhaps for coils depending on what tank I am using.
