@Marcus1970 something to make you laugh, Pbusardo's review of the Coolfire IV the bit at about 9 minutes:
My but he waffles! ...glad you gave pointers to the relevant bits:
Had he not read any pre-release stuff on these? I'm surprised
he didn't know about that on/off switch seeing he gets to review so many. Easy that anyone that hadn't already read about it wouldn't initially realise, but I'd expect him to have done a bit of homework before starting.
Seeing I'd read/scanned the blurb on the pre-release info on sites to sell it, it was the first thing I did with mine because they did show that on/off switch - what I then needed to realise was that it still needed clicks to actually turn it on properly, but that was common sense after having a 'few' other mods.
EDIT: He makes a valid point at about 38 minutes about where the fire button should have been - I was thinking exactly the same thing yesterday
I think that's a matter of personal preference - doubt it's a hand size thing because my hands aren't huge, but they aren't tiny either - anyway, I tried mine and pretended that fire button was on the curve ..didn't feel as secure in my hand and didn't feel as naturally easy to press it either.
I tend to use the outer edge of my thumb or the side of my thumb near the joint because when I got a MVP2, I found the button a bit tough to press continually and it actually damaged a nerve in the centre point of my thumb.
So, for me, the button where it is works fine, but I'd probably get used to it if it were on the curve
Around 18.50 minutes, he gets to the VV/VW he didn't mention the instructions not being clear about how to switch it, but does show how it's done.
Those written instructions need correcting - not everyone will find this video type of information easily.
I agree with is comments on the actual adjustment of the voltage or wattage at around 23 minutes ..a bit awkward
