I happen to have 3 Kissbox Classics with batteries and Janty Passthrough's. I Imagined that the Jantystick would be better so i bought one (preordered even) and was appalled at the quality and workmanship of it. It did'nt work properly from the very beginning. I got a replacement which was ok for a while and then started leaking and gumming up the switch. I have not been offered a V2 but cannot see how it could not have the same inherent design faults. The leakage will still affect the connection to the usb port leaving the Stick underpowered resulting in mouthfuls of Juice which give the user the need to carry with him a lot of tissues, a spitoon and plenty of toilet paper and medicine for a sore gut. Also a pair of pliars to extract the Atomiser out of the damn thing.
The Jantystick is a solid product, but the sheer numbers of how many there has been produced make it impossible to avoid certain malfunctions or error-filled individual shipments. These are hand made; they are being put together by hand - so yes, problems can and will occur.
As for the leakage, this is why the V2 was built; and you also mentioned you preordered the Jantystick, making me think that you are talking about some of the very first batches, which apparently did have some quality issues.
And as for the workmanship - the Jantystick was ment to be a workhorse, something that would last for a long time, in terms of battery power. It was never built to be the most beautiful e-cigarette ever; and its opponent in this case, regarding looks, is a metal tubing with a nice finish. That is an unfair opponent, seeing as if the jantystick had been made in metal, its price would have gone up several times.
So there are alot of reasons why the Kissbox looks, and acts like it does; and why its price is what it is.
And, then, you have another product, the Jantystick, which also has its features, its ups and downs, and its own pricetag, which for what it offers, is a very compelling price.
Maybe its not for you; good thing you have found a vaping device that IS for you then, in this case the kissbox. But it does not make the Jantystick a lesser device for everyone else in the world; alot of people love it.
Having said that, im sorry you had a bad experience with your Jantystick, because to me its the reason i dont smoke analogue cigarettes - its *that* good in my eyes. But im happy you are enjoying your kissbox.
