Well i have the Itaste clk 1280 and ive been using the kangertech protank 3 v2 mini with it and it stopped hitting. i just changed the duel coil with another one to see if that would fix it which it mad it hit again but, it has a weird taste and doesn't seem to hit as good as it did before. don't know what could be causing this so anyone who can help that would be great
