I use it regularly in June (we cherry) after a picking session, devote the equivalent in time for stoning before freezing or into pies or jams. We have this unit for 10 years, after washing the fruits (cherries or plums), you must pass them one by one under the punch mounted on spring, core falls into the bottom container and pitted fruit rolls by lateral gutter in a small bowl. Efficiency: 99.5% there is still some kernels that pass through bowl. I prefer to avoid congestion only place a small handful of fruits in both the receptacle and to release them one by one by holding the left hand. The small rubber gauge has since been replaced by a spare part crafted by myself in a plastic sheet after a bottle of milk. Wash and dry the material completely dismantled after use
