As long as your 808 is automatic, you can use the greencig carts. They are a bit more expensive but 100% different in vaping. Super smooth with no chemical taste or harsh undertone. I got mine at lecig.com. the have a greencig section under the carts. I had mint, which is more minty than menthol. I haven't tried the others yet, but it is possible to refill & reuse them to save some cash.
Anyway, good luck.

ps - the manual 808 batts won't work with the greencigs because they don't have a notch in the center of the battery which is needed for the airflow. You may be able to obtain an adapter but I get by with my D1 batt from lecig and I have a 901 automatic batt that also works.
