Fan of The Finest brand, Apple Peach Sour is a great alternative.
I currently use 6 of Finest's vape juices (including Blueberry Lemon Swirl, Mango Berry, Berry Blast, Apple Pearadise, Straw-Melon Sour, and Apple Peach Sour,) and all of these flavors are, without a doubt, my very favorites in my collection. The flavors are bold, true, and delicious. They work wonderfully in my Smok Novo 2 pod system. I am a repeat customer, and will definitely be restocking Finest flavors in the near future. I give Finest vape juices an 11 out of 10!
