I know a few of you own these, so kindly chime in. Any issues? I realize there’s precious little to it, but for me that’s its appeal. A few questions:

-Does the machine bolt stay put, or is Loctite required?

-Given that you must have to tighten the bolt enough to prevent the keys from rotating around, are they still easily “deployed”?

– Any risk of the keys mangling the threads over time?
