Glad you are having such a good experience so far! Keep us updated!
I'm a new Halo customer, just got my G6 kit in the mail this morning. Yay! Been happily vaping now for several hours.
The SubZero flavor is certainly nice. Very strong menthol taste even at 12 mg strength. I like it quite a lot, but it probably won't become my go-to vape. If you're familiar with the Menthol Ice the sensation is very similar, but the menthol taste is much more pronounced, as is the crisp sensation in your lungs which lingers for sometimes even a few minutes. Most pleasant, would probably be really good for those days where vapers have a 'tasteless' day perhaps, or if you're congested/sick. Some may like the more powerful taste as a go-to vape, but I think I'll likely be keeping it around but not as a primary more as a treat or a wake-me-up.
Personally, I liked the more toned down but still frosty Menthol Ice flavor, but the SubZero is without a doubt very tasty and will likely keep a place in my future lineups.
On another note there was a poster who mentioned that he was mixing a few drops of SubZero to some of the tobacco flavors such as Prime 15 and Torque 56 with very pleasant results. He mentioned it was a pretty close match to Marlboro Smooths. Worth a future try and a suggestion for you guys who prefer the Smooths to try out.
Off topic and Caveat:
I'm a new vaper, and haven't taste tested much yet but so far all 3 of your Halo flavors I have tried have been quite, quite satisfactory. Very pleased. And I still haven't killed my first battery after a couple hours of vaping. So glad for a cig-a-like version I purchased this unit. Kudos Halo, and you've definitely earned me as a future customer. Rapid shipping and 3/3 tasty juices means I'm a pretty happy puppy with you guys from the start. Keep it up! Looking forward to experimenting with your other flavors in my sample pack and playing with some mixing. Should have ordered a few more blank cartos....fixing that now. And getting more SubZero while I'm at it.
