I just finished off an Herbie session of OL oil at 445 using Japanese organic cotton. It's what I had purchased for my EVape/cig to quit smoking. Over 6 months without after almost 20 yrs of the habit!!!! Anyway the JOC worked perfect with no taste difference or visable scorching of the cotton. I put a decent drop straight on the cotton and completely wrapped it so it didn't touch the screen. Got several good rips thru the water tube. I think this might be a new favorite. Just wanted to share....
