Well it's time to trash this one. My Mom is working real hard to get some vapor.
It still works but she has to draw very hard to get vapor. I'm guessing that is a good indication to change it out.
When all is said and done, we got about 25 fills on this mini tank with Tribeca only.
That's a good run I would think.
Don't forget to clean the battery, including the top and air holes.
You will see Two small air holes on the side of the battery where the mini tank screws on.
Take a safety pin and ream them out to make sure that they are not getting blocked by the small amount of juice that will build up over time in the battery connection point.
They can cause the draw to become much harder if they become blocked.
