I've just purchased new BVCs for my mini nautilus. The holes are much larger than before and the taste is very bad? I have checked that they are genuine and they are.
They start off with a very burnt taste depite being primed correctly and left to soak in and they also irritate the inside of my mouth and throat?! As if tiny particles are coming through. Have you changed the wicking material in these? I cannot use them and have had to rinse out some old bvc s and use those instead.
