HHV is pricey but her juices aren't bad. Price for juice is something you've gotta see past because sometimes you have to pay more for better quality. The cheaper juices are going to be watered down or worse, they'll utilize cheap base flavors. Yuck. The latter is worse. Some vendors have cheap watered down or light PV/VG heavy juice but use GOOD flavorings, like ECBlends. So, there is a tight rope that you'll have to learn to walk when buying juices. Weigh your options... Some vendors use cheap flavors, some use too much PG/VG. Thats where the "value" in the cheap price comes from... But the over-all value of the juice decreases because you wont truly enjoy it.
Idk, HHV is pricey and I've only tried 1 of her juices, and it was very light, but tasty none the less. It was a tobacco flavor. A bit perfumey for my tastes and a bit too bitter for a tobacco in my opinion, but it was addictive and yummy anyway lol. Not too shabby. I would rather pay more for a juice that I'll enjoy than pay less for a juice that ... come to find out ... I can't even vape it, its so bad.
Then there are CHEAP china made juices that I love (but I like to mix them with heavier juices because they are so light and watery) DK-TAB and RY4 are some of my favorite cheap juices and they make great mixer juices.
AS FOR BANANA, boyyy, GrimmGreen on youtube absolutely LOVES banana and hes going to be releasing a line of juices soon. Very soon actually. His juices will be called "Namber Juice" and it should be released before year's end... He is a banana juice connoisseur so I'd have to guess his bananas will be great. Uhm, the cheaper banana breads and banana juices are going to utilize cheap banana flavoring more often than a more expensive company would use them... But, even these candy kind of banana flavors are good after a good long steeping period. When I first bought banana bread from TopVapor, it was terrible. It tasted like a stale runts banana candy mixed with soap. Now, 3 weeks later, I am tasting a more banana baked good, still not even close to a true banana bread, but the candy type banana is muted and it started to taste more like a warm ripe-ish bananer.

IDK. Its not throw up bad! haha.
But, generally, if you want a TRUE to it's name flavored juice, Boyyyyyy you better pay up! haha. I mean juices are not easy to make. Many of the best known juice companies employ CHEMISTS to formulate their flavors and expert juice makers to mix the juice.. So the price is in the juice, its there. An expensive juice company's juice is going to taste like what the label says most of the time.
Now, HHV is a newer "expensive-ish" company... But they've gained a lot of followers and fans very quickly so I am guessing that they are doing something right with their juices. Myself? I have tried more CHEAP juices in my lifetime than the expensive juice company's juices... Because I've been broke throughout my vape-lifetime, lol. But, I know which companies sell the good stuff for the most part.
If you want TRUE TO LABEL flavors... Backwoods Brew sells fantastic Juice. As does CopperCreek. CopperCreek juices are fantastically exact to the label's name. Just do a search for a CC review on google and you'll soon find that 85 to 100% of the time, people are raving that they can actually taste the cooked pumpkin and each individual spice in their pumpkin pie. There are a lot of juice makers like this... and then there are fly-by-night juice companies that gain all the popularity on these forums, and they have the expensive prices, but they pale in comparison to some of the less spoken of companies unfortunately. The new members like the name of a new company thats advertizing here for a month, the ads leave, but the new members swear by the new companies without ever having tried some of the artisan companies that have truly contributed to this community in the past. So please keep that in mind along with price when ordering.
This is my 2nd user name here and I've been here at ECF for around 4 year now. I've seen a lot and read a lot and posted a lot and said a lot haha. But I can promise you that there are fantastic, trueee banana flavored juices out there. I recommend copper creek's entire juice line simply because I know that each review I've seen of their juices was a fanatical review then & now. PS they do have banana.

Hope I've helped.
