I have a Volt x2 Clearomizer, and I love it, but I want something just like it, that holds more juice, but has a natural 808 threading so i can use it on my volt x2 or regular kr808s. Can anyone tell me a product that fits this description? Ideally, something that holds 2ml+, that's reuseable, easy to fill, preferably with no extra hardware, and doesn't cost a fortune.
