Query: Good but cannot compare with a power citrus press

As a manual juice press this machine has several advantages:- juices reliably- easier to clean- less to break, will probably last foreverBut as I found out, it cannot compare to a powered reamer in juice output.I just did a side-by-side test with this and theBreville 800CPXL Die-Cast Stainless-Steel Motorized Citrus Pressand the Breville got more juice out of the orange and nearly twice the juice from a red grapefruit. The reason is that while this juicer simply applies downward force, the reamer in the Breville squeezes out little bits as it rotates. With the Olympus you also get some bitter taste from the peel because the force here is much greater.I realize that the Breville I used is not commercial grade but they make a commercial variant which I will be buying. The difference in output can make the difference between breaking even and making a profit.Ordinarily I would opt for simplicity (the Olympus wins) but here efficiency is more important.
