I rarely watch any vape vids on youtube any more. I have to actually be looking to learn how to do something to be motivated to watch a vape related vid and I seldom make any changes to how I do things vape related. -- For informative REO stuff smxdrifter has been worth watching. When I feel like being experimental with my coils, now and then I'll watch a rip trippers vid...or if I really want to make sure I get a complicated build right I might watch it done by several youtubers.
I do agree that there are some really entertaining folks going over some really excellent vape related material on youtube and I used to watch a whole lot of vape vids... but these days I don't buy new gear, I'm not very curios about new gear, and I don't really have any intentions of replacing any gear I have... so vape gear reviews don't aren't nearly as fun to watch as they used to be. --- So, these days, entertaining isn't necessarily what I'm after. Dry tutorials are often more useful to me.
