Andy,
Thanks....and I will work on improving my product! I am working on a new atomizer and battery technology.
We don't bottle our juice because of the large population of 'misdroppers' the misdroppers are the people who were likely introduced to the product by a vapor geek (someone who researches e-cigs and knows ALL the ins and outs about the technology). The misdroppers have the HOW HARD COULD IT BE mindset when dripping liquid (this is the largest percentage of the population I might add). Consequently equipment, namely atomizers, fail when they "MIS DROP liquid and destroy the atomizers....then quality suppliers of product who stand behind their product suffer.
People who hustle their juice with no warnings or regulation are doing the industry an injustice. As we all know, the population as a whole is usually inept when it comes to anything that takes any skill or dexterity. We take that out of the equation by not providing our liquid in any other form but in cartridge.
Ask anyone in the industry how our customer service ranks and I guarantee it's number 1 across the board. However, we likely won't be able to keep it up if the charlatans keep marketing e-juice without any regard to the hardware and, cosequently, the financial ramifications of them selling juice to misdroppers....
FYI I don't know for sure, but I doubt Dura 510 carts will work. We have an atomizer that has a slightly larger circumference than a traditional DSE103....also, those other juices have stuff like ethyl heptanoate, which doesn't bode well with our atomizer life....
Being a supplier and one who seems to have done some research, then you should know that a 1000mah battery is needed to make a PV work well instead of the undersized batteries that most suppliers provide. And a manual switch instead of an auto switch that cuts off after 5 seconds also provides a much better experience. And with a manual switch you don't have to worry about liquid leaking into the battery compartment and damaging the switch. There is a reason that anyone who trys a device like a screwdriver or similar product states it is 100 time better than this undersized, auto switched devices.
