Hello Testing123. Right now I have the 6006 and that's all I've tried so far. In my research, I liked the parasoy blend and since I started with CandleScience, went with 6006. However, I have discovered that FlamingCandle is not too far from me and was going to look into the possibility of picking up my supplies vs shipping. With that being said, I'm curious about how the Problend 600 stacks up to the 6006 (other than the messiness lol). Any information you are willing to share is appreciated.
