Vapenstein had an initially not-quite-good review of T56. He revisited that review with another review, recanting his previous review and giving T56 a good recommendation. He's claimed it's his all-day vape on occasion since then, as well.
I got a recommendation that when first receiving an order of T56, to open it and let it air for a couple hours, then take the dropper and circulate the juice but drawing it up, and releasing it back into the bottle several times, exposing it to air. Shake it well and do it again.
My T56 has been delicious since day one using that method. I left it open overnight the first night, and the next morning I think it tasted even better.
It's my all-day vape, no question. I have five tobacco flavors from BWB, all highly-recommended on ECF and elsewhere, and Halo T56 beats them all, IMO.
