Let's see.....
Blueberry Pie from FSUSA. Got it free as a sampler and thought it was the most disgusting.... ugh. It was so bad, I still tasted it in that attie for weeks, even after a 24 hour soak in mouth wash and a lot of dripping a minty flavored juice over it.
Current RY4 from FSUSA. I think they added chocolate, and it is *not* what I've come to expect from a RY4. Whatever their chocolate flavoring is, is absolutely disgusting. It's a distinct disgusting flavor I've tasted in their chocolate, peanut butter cup, butterfinger, and other chocolate flavored juices. Putting it into a previous top 3 favorite juice just angers me.
Orange Crush from FSUSA. Actually, orange anything from them. Their orange flavoring tastes like Orange Glo furniture polish. It's very chemically and disgusting.
A close runner up: This horrible (180ml) bottle of RY4 I've had for a month from bluemist. The sampler I got 6 weeks ago was amazing, but something about this bottle... it's either not there yet, or it never will be. Either way, even after a month, it's gross.
"That's all FSUSA!" you may be thinking. Yes, yes it is. I've tried liquids from thevaporpro, FSUSA, and bluemist only. Bluemist was my 3rd company where I finally found liquids I greatly enjoyed and stopped looking. I've dumped over $150 into samplers before finally finding flavors I liked. That was enough for me to say it's time to stop looking.
