I juice a lot of oranges on a regular basis. I have tried manual reamers and electric juicers. I was excited to use one which could apply a lot of pressure quickly and with less effort. The only problem, and it is a big one, is that the juicer leaves a large portion of the flesh unsqueezed. When I use an electric juicer/reamer, there is very little flesh left. With this juicer, the top does not come down far enough onto the removable cup cap to squeeze the whole orange. As a result, you will waste about 25% of the juice. This problem is so obvious that I can take the juiced halves and squeeze more juice out with my bare hand. I will be seeking a refund. I am very disappointed. I can't believe this product is on the market with such poor performance.
