Ok I have recently ordered from them. I got Butterscotch, Root Beer, Cheesecake, Lemon Meringue pie, all with 35% flavor boost. The Butterscotch and cheesecake, in my opinion are very good. The root beer tastes really chemical-y and I haven't tried the LM yet. I am going to order some more juice from them, different flavors because I like the price and was impressed by the flavors I did like. They also have good customer service, in my experience.
So...it may be hit or miss depending on what you order.
