dewberry cream was definitely one of my favorites along with some of the other kilo products--cereal milk and tru blue. Since I only found out the other day about high levels of diketones in kilo's eliquid, I really don't have too many other favorites currently since their products were my go-to all day vapes. I did just pick up some new juice from moutainoakvapors.com though --so far I like their creme de la crema series, but I haven't tried everything yet.
By the way, even though diacetyl, pentanedione and other diketones are supposedly bad for you, they are probably still a lot safer than smoking cigarettes. So it's your call if you'd like continue vaping dewberry cream. I just bought 120ml of it along with cereal milk from kilo last week. I'll probably vape them still, but just not everyday, all day like how I used to. I guess moderation is key here.
If you're interested in finding vendors that don't use diketones in their juice, there are a couple of threads in this section that have an on-going list.
