I've never had an issue with mine. I have wheels on a few of my sabers, including my main "spinner", a Dark Catalyst. I've never had any issues with it. Had one on an Aeon V4 as well, it was also never a problem.
I'm glad to hear is hasn't been a problem. I'm saving up for this one, thanks.
If you get one and you don't like it, it is removable with the right size allen wrench. I have one removed from one side of my Menace staff. There's a hole there so I can put it back if I want.
How bad does the hole look? Hehe, we are after all, getting really cool looking Light Sabers. Looks count
Thanks,
