Query: sore hands and metal shavings

This juicer might be for you if you only plan on squeezing a small amount of fruit. However, trying to get enough limes pressed for a pitcher of margaritas proved to be too much. Not only were my hands sore, but the cheap gears left metal shavings in the juice.I plan on returning it and stepping up to a real juicer.
