Query: chinese junk

Some years ago, I replaced tuners on a guitar with Ping tuners, and they were absolutely great tuners, stayed in tune forever. I just recently purchased 3 sets of these Ping tuners, and they are absolutely worthless junk, with even nylon bushings. It is hard to believe that we have sunk to this all time low of importing junk .Amazon you should be ashamed of your self, and I won't be buying anything fromyou in the future.
