I am enjoying my Xhaler at 5-6 volts and just ordered an SB. One thing I found strange is that I do not really care for the taste my favorite flavor juices at high voltages. My favorite flavor, MFS blackberry, seemed much too sweet and not somewhat sour as it tastes at 3.7 volts. It seems that all the sweet flavored e-juices, even the hv e-juice, just tastes too sweet and overall does not taste very good to me at higher voltages. However, believe it or not, all the tobacco flavors seem to do extremely well at high voltage (at least to me). For those of you that want a vaping experience to closely simulate smoking a cigarette; for me vaping tobacco flavors at high voltage has been the most similar to smoking an analog as anything I tried yet. I just hope my taste change because I really like the TH and vapor production at higher voltages (and I have a lot of sweet flavored e-juice).
