In my opinion there is nothing wrong with making money, or getting toys to try out for free, etc. No one faults this.
It's just odd that you couldn't find anything at all to say positive about such a great PV, yet there are others out there that you interesting enough can't find a single thing wrong with. All excited as you explain the pushes required to measure the Ohms on a Vari, but ONE click on a Darwin is too much?
All the user has to do is charge the Darwin every once in a while. No, you can't swap out the batteries, but you don't need to swap them out. Just plug the thing in and keep using it while it is charging (another thing I don't remember being mentioned in the review).
Easy to use...
Very low maintenance...
VERY POWERFUL...
One of the lightest PVs in its class (you won't find lighter/smaller a 1100mah(or more) 3.2v to 12v variable up to 3amps device ANYWHERE).
Superb warranty on both the batteries and the unit itself.
The Darwin with 1 year warranted batteries rated at thousands of charge cycles (around 2 years) and 2 year unit warranty cost similar to other high end mods with no batteries, no charger, and no extended warranty.
The arm that you hate actually gives it nearly 180 degrees of flexibilty in which way you point your atty while vaping, meaning you can flip it around and use it over handed, or under handed, with a variety of button pushing fingers. You failed to mention that your big fat tanks can be put on it at 90 degrees, allowing you to lay the thing down flat on its back...a very steady platform for big tank users.
The play in the arm is there for a reason. If your hand slips, or you bump into someone, or get bumped into while vaping...the arm has a little more play in any direction, instead of your teeth or jaw. Yes, even the fraction of an inch play going side to side is enough to help prevent chipping a tooth.
If you don't like the button, that is a fair criticism, but it would be nice to have a more accurate description of it. The quality of the switch it top notch...one of the highest rated push buttons on the planet, bar none. Actually, they are NOT hard to push. They just have a tactile click to them. Measure the force with an appropriate tool, and compare it with other PV switches out there. Honestly, the difference in force required is very small, and you might be surprised to see how the various buttons stack up in head to head comparisons in terms of 'force' needed to make a good contact.
On the moving wheel thing. Again...I rarely close the arm on mine at all. It rides in my car seat with full tanks and such. Never had a mis-fire with the arm up. Things rub up against it. It flops around. No dial movement here. Of course if I intentionally BRUSH AT THE WHEEL it's going to move. You MEANT to move it duuu.
Juice/liquid/dust in the PV.
It can happen, but it's not likely. If it does happen, it's not likely to damage anything, as the internal bits are sealed with a protective coating.
But maybe he will soon.
but one things for sure,,Darwin is gonna be on the end table by the bed and I'm vaping before & After Always !
Good point. Thanks for the bump though
