im really surprised at these posts. I can't taste the camel thru my 510 at all, just plastic. When I use menthol I can taste it a bit more, but I'm still getting a very plastic taste to it. I have to top off after 10-20 drags which bothers me a lot. And sometimes, after just one or two drags on a topped off cart AND primed atty, ill taste the plastic and notice that my filler fibers are attached to the atty or that the cart is melting. As I've said in about 8 different threads, I am quite dissatisfied with my 510 as of now. Im hoping the 801 and/or 601 will be much less work...
