Not really although it was pretty gross to actually see the carto getting all gunked up. For some reason the coffee flavors I get from
mad vapes turn really dark (they start out as clear) really fast and when I used them in the clear EMDCC it was fairly unattractive. Other than aesthetic issues I didn't notice any performance issues. My other clear one I bought I have
tobacco flavors in it that I use occasionally and it's still pretty clear and putting out massive vapor and TH like the day I unwrapped it. I can see that if you are really really hard on your E-Cig...like you drop it a lot...the clear one could crack a lot easier. They are a pretty thin plastic.
I won't
buy the clear ones again. For some reason I like the look and feel of the black ones myself. Let me know if you have any more questions I can try to help you with.
