I had my igo m for about 2 months ago but when I recently got it, about using it for a few weeks the center post started to spin freely after later on weeks it's came off and so I pushed back in place. It didn't bother for awhile because it still made great connection but after now it gets annoying, every time I make a build and but the leads in the post would pop off. So any ideas how I can fix it and make it stay in place and not spin freely?
