I got started at MBV. Probably spent around 2-300 bucks and tried about 20 juices. 2 were good, 3-4 more were okay but not something I would vape repeatedly all day, and the rest were nasty. Extensive steeping required or you'll get nasty soapy aftertastes.
The main knock on MBV is their consistency. I stopped ordering from them when the 2 juices I liked and reordered were disgusting on the second/third bottle. The two that I liked Banana Nut Bread and the Cinnamon Roll. The BNB tasted like soapy tobacco on the third bottle, and the Cinnamon Roll tasted like straight cinnamon juice on the second bottle. Most of their juices require 3-4 week steep to get rid of the chemical taste, but most of them never got good.
Now that I've moved onto another vendor, when I try to vape their MBV juice it makes me nauseous. Not just from the flavor, but I guess once you've been away from their ingredients for a while, your body has to get used to them again.
With that said, they have incredible customer service. They ship quickly, have a livechat, and if there's a problem they fix it right away. I've had a small problem 2-3 times and they remedied it with the quickness either by sending me a new bottle or giving me a store credit.
One thing that drove me crazy was that the flavors were weak unless you got flavor shots. But it's up to you to decide how many flavor shots you need without tasting them. So basically you're becoming a make-shift juice chef without ever intending on being one.
I purchased most of the best sellers and was shocked that I pretty much hated all of them. Nice flavor selection, but with so many choices it makes my head spin. I actually prefer when vendors narrow it down a little bit. When you've got 3-4 flavors with the same taste profile, it gives you a headache trying to decide which one.
I mean Cinnamon Roll vs. Honey Bun. Cinnamon Roll is basically Honey Bun with stronger cinnamon. Banana Nut Bread vs. Bananas Gone Nuts. Bananas gone nuts is Banana Nut Bread with Cinnamon added. And most of the flavors, especially the fruits, are very artificial tasting. Basically like vaping candy.
Sorry for the long post.
