'Pet Peeve' about Dust Covers I accept, obsession seems unfair.
Like you, I remove my dust cover during play, advise others to remove them, my peeve is that the majority of the time these fanciful and expensive creations with high precision parts are off, and leaving them out to airborne contaminants is unwise, selling them without a dust cover seems irresponsible to me.
Bearings wear, that takes a long time, but they are effected by airborne contaminants to large or small accumulating degree, and evidence of lack of need for AS reveals both.
