I've used them for roughly 6-8 months, both are in perfect mechanical condition. Minor scuff on washer.
I bring home every brand that I sell at my store in order to do a real life test on their performance, reliability etc. normally I only keep them for about 30 days or so, but this set I particularly liked. It's time to test my LG line, so this set has to go. Still has 4 ish years of manufacture's warranty.
