I do not own a V3 stick, but I have 2 x JoyE V2s. I do not know if the individual has a JoyE or a knock off, he doesn't say. Although the V3 was out at the time, I opt for the V2 ebcause of the reported switch problems with the V3, including the ones from JoyE.
The thing that needs to be remembered, is that when this
device hit the streets, it was quite innovative. There is no doubt that any
device that utilizes a 10440 as a power source is underpowered.
The Stick comes with a native JoyE 302 atty and not an 801, and yes there is a difference between the two as far as performance. I did not particularly care for either the 801 or 302. I did however enjoy the 510 adapter and this
device rocks as a 510, comparatively speaking against an 801 series atomiser.
It was purchased for it's stealth abilities and mine is still used to date, in a 510 configuration with both attys and cartos. It is not an all day device nor is it intended to replace what is currently on the market. The market has made leaps and bounds since then, and that is relevant and not mentioned in his review.
I don't lend allot of credence towards folks that do revues on borrowed stuff. But that is just my opinion.
