Purchased 2 Spinners (1300 mah) and am having the following problems: 1) Top threaded section gets stretched out and my Vision Vivi Novas fall out. (Could be threads on Vivi Nova get worn down, too.) I had to hammer around (scratching and nicking it) the top to get it to tighten up. This also happened with my KGO battery. The metal must be very soft. 2) I don't like the cut-off (11 sec.?) for long draws. Has this been eliiminated in the current model? A couple vendors I've looked at don't even mention this. 3) Drop one on it bottom and the battery is loose and button is stuck. Suppose I have to throw it away. I really wish they would not make these things round. You set them down and they roll off the table. Could easily be remedied with a knurled knob with flattened sides. Anyone know of what I can get that fixes the above problems? Otherwise I'd be very satisfied with the Spinner.
