This cherry stoner or pitter is for home use in removing the pit from fresh cherries. It is complete with manual and no parts are missing. I only used it a couple of times. I was pleased with the frozen cherries. However, one must engage in a consistent slow method. If you put them through too fast, some go through with the pits still in. Also, you should clear the area of unused items as the cherry juice splatters some and stains. I'm selling because I'm leaving cherry country.
