MBV has a great website and a wide array of juices. The products are very cost-efficient (I hate to say cheap) and for the most part, they taste as advertised. You won't find any overly complex juices at MBV, but that works for a lot of people. The ability to choose all of the common options is there and they make ordering easy. As an added bonus, there is always a valid coupon code to save 10% on their already wonderfully priced juices.
I've ordered a 10 or so flavors from MBV and I have thoroughly enjoyed 3 or 4 of them. While a 30-40% satisfaction rate wouldn't normally be something to talk about, the juices that I didn't enjoy weren't because they didn't taste as advertised.
It's also widely known that MBV will often throw extra juice in your order as a thank you sampler. One thing to be said for this is that they don't always match the free juice to the options picked on your paid juice. It's a great act of customer service and I'm not one to be ungrateful. Unfortunately, I've vaped it forward on every one of these that I have received because the Nic content was too high for my liking.
I would say that MBV is a great vendor for new vapors. As we expand our gadgets and our tastes, it becomes apparent for a lot of people that there are better options out there.
