Carmel Tobacco is my fav but it's thick,kills atomizers and has to be dripped..I build my own atomizers for it out of CE2 parts though and use a DoD. I also like Tutti Fruti (2nd fav),Bubblegum and Blueberry a lot. Yes I have a sweet tooth lol..I use there Coffee with my morning cup.
I haven't tried a lot more but a few..I don't like there apple flavors much because it tastes like a green apple. Carmel Cream is just too rich after vaping it for a short time..Kick-Azz Caramel is good but on the rich side too. Minthol I liked a bit even though I don't like menthol (only tried it because I got some for my dad).
Look at the reviews as I tried to stick to flavors with 4 stars or better. I read they used to send free samples out orders but stopped because some people complained..I wish they would send some out still because I would like to try some more..probably next order I will try 1 or 2 but I'm stoicked up for at least a month maybe 2. They do sell E-liquid packs of 5-10ml flavors for $14.99 that would be good for trying some and they add new packs every once in awhile.
I'm pretty happy with what I vape right now but I plan on trying new juices from time to time. I only buy from MadVapes at this point too (started vaping last June) and I haven't felt the need to buy elsewhere yet..there juice prices are very reasonable..under $8 for 30ml bottles..there overall prices, customer service and shipping are all really good.
The way I do it is try to make my orders every other month and spend over $75 there so shipping is free..so sometimes I will get a small bottle or 2 to try out with my regular order..good luck
