I must have acidic saliva as my mic grilles seem to go rusty after a year or two. The official Shure replacements are prohibitively expensive, but I've always found Thomann to be the cheapest supplier.
I can't say much about the product other than it's of good quality and is identical to the one it is replacing.
Great customer service and speedy delivery though as always.
