I'd surely appreciate some advice on the new Herakles Plus that just arrived to me an hour ago .... firstly I'll say claimed changes are indeed present as the plus has even greater airflow, a cloud lover's dream in sub ohming, but I need a little advice on the top airflow. Watched a 'pro' utube review where the guy comments on his testing with the top airflow 'on' and 'off' ..... but even with my glasses on I can't see anything that makes it clear which is which ... maybe its because I bought the black one ..... If I had a needle (which I do not ) I might drop it in the oval holes to see when it fully enters but maybe theres marks for setting that I'm not seeing ..... advice appreciated or just tell me how you yourself know open from closed on the top (mouthpiece) airflow adjustment, thanks. By the way, filling from the top added method is simply terrific and fast, and just adds a slight touch more room for juice. Only thing they need is just a one page manual.
