Whats up guys, new/old member here from so ca. So i have a pro tank ive been vaping on for 2 weeks. Im using ry4 from my local shop, it tasted great to me so i baught 30ml, after about 20 or so ml it started to taste funky. Like a stale kida metal taste. Ive tried everything from new heads, clean tank, even went to my shop the girl said it taste fine. Another guy said it did taste a bit funny to him. Any thoughts would be greatly appreciated! Thanx, Joel
