Are there any honest reviewers?
Maybe. But it's irrelevant to me, and here's why.
First, I'll talk about e-liquid reviews, which I don't watch. With all due respect to those that do them, I really don't care what you like or don't like, my tastebuds get the final word.
Now, as to devices, whether they be mechs, mods, atomizers, wicks, wires, tools, of one type or another, I watch the videos simply to SEE the device up close and personal before I shell out $200. I want to see it in action. I want to see a build on it. I want to see it run through its paces.
I'll also get on the forum and Reddit to see what the chatter is.
And I don't just watch ONE review. Before I bought my KF4, I must have watched well over a dozen videos before making the final decision. I think the Squape R had been out for close to a YEAR before I bought mine (in the classifieds here on the forum, of course).
Now, there are some reviewers that are better than others at pointing out the pluses and minuses of equipment, and those I tend to pay attention to a bit more than the others. Some reviewers I can turn the volume off on and just watch what's going on.
