The flavor is exquisite. It's not quite the flavor of a real peach, but it's the closest artificial flavor to a real flavor I've ever tasted. It's like a really good peach candy without too much sugar and with no artificial sweetness. Like peach candy from decades ago that you can't find anymore.
The only reason it's not a perfect score is because it doesn't last as long as other products with the same amount of liquid for the same price. The equivalent puffbar is the same price and lasts almost twice as long. The puffbar also has a similar great flavor. But the puffbar has been less reliable from my experience. I've had several issues with weird flavors and malfunctioning atomizers in the puffbar, and that led me to the swft brand.
If swft would sell the juice on it's own I would buy it in a heartbeat.
