As already stated, no issues with gap for the Voodoo knob. The only problem I had was that I bought the brushed finish one and after a few weeks it’s all scratched. I wear a wedding ring and I’m not taking it off just to drive my car so I think I’m going to have to get some fine grit sandpaper or wet & dry and try to polish it up so it’s all a uniform finish. Real shame as I liked the brushed finish it initially had. I noticed they had a matt black version too but I’m worried that’ll have the same issues but look much worse.
