Well, it's (they're) holding up great. The brass one needs more cleaning (for looks) than the chrome. Some small amount of
juice residue can collect between the layers; but a quick wipe every few days is no big deal. I do like them!
I never need a hole smaller than 1.3mm, and 1.5 was the biggest I'd ever gotten. So I drilled the atty out to 1.7mm, and turn the ring to it's open slit to free up that size.. Then I drilled 1.6, 1.5, 1.45, 1.4, 1.3mm holes. I don't really need the variations of .05mm, but I had room.
I don't think Rob has time to deal with this kina' stuff!
