“This little pod is great, never and issue. To fill it without spilling I would recommend a needle point bottle for the small fill hole. The other thing to keep in mind. It works the best if the air adjustment located at the bottom that holds the coil is kept completely open to avoid flooding the coil. When filling the pod its upside down, and you can see how much juice you're putting in. I would recommend to only fill just a tad above the bottom of the black mouthpiece, "a tad" just when you begin to see the juice. When its turned right side up it will show full. If its filled more than this you will get spit back. Again if its filled with juice that covers the entire window the spit back. This will put the juice in your mouth, "not good" and that isn't what your looking for. What is happening here is that you're putting juice in the mouth piece.
Its easier to put in just the right amount to get that deep hit that's fulfilling. Hope this helps?.”
