I just got 8 stardusts. Some hit well, others have wicking issues, some have barely any of the ridged metal on the bottom above the bottom cap, others have twice as much. Did I get two different versions or are they just inconsistent. They are all V1 short wickers. I had heard that the Version 1 was easy to take apart, and that later Version 1 (v1.1 we'll call it) is harder. Could it be the difference between the amount of ridged metal holding the tank together at the bottom? Do I have all V1s that are inconsistent? Or do I have a mix of V1s and V1.1s?
