Allow me to point out that this "reviewer" 1) has not participated in this thread previously, 2) has a post count so low that he is NOT a contributor to FC so much as a passer-by (the previous posts were almost exactly a year ago), 3) shows up when there is a video to promote, 4) knows little about the vape he is reviewing or how it works (see previous post), and 5) only showed up to say "go click on my video and give me more views" [and hadn't been back since].
I had originally given a like to the post, but I have now removed it as not being worthy.
