I've used all three burst duo flavour offered by vape360 to the completion of the bottle. When it comes to flavour burst duo provides a starburst esc flavour without being too over the top. This takes me back to trick-or-treating as a kid. All three juices have the same two flaws to them however, all are likely attributed to higher sucrose levels. The first flaw and the one you'll notice quickly is that the back of your throat begins to feel dry or sticky while vaping this juice, the second is your coils are likely to burn out before the completion of the bottle (at least I've noticed this with both crown 3 coils at 85W, and valyrian coils at 110W) of course the second point is dependent on your setup and the way you vape/prime your coils. Overall, this is a fantastic series and you should definitely try it.
Thanks for your feedback, Gabriel. Burst Duo is a great series. We're happy to see you're enjoying it.
