Nevertheless, Rav Blumenkrantz, who is not known for being a maikil, in his Pesach book of 2007 lists some of the kosher shavers.
Just one comment. For a few years I had used the Remington 850, and it worked well. I thought it was lost, so I looked in the book and bought a Remington 950. It was terrible. Cuts very poorly and hurts face very badly. It weighs much less than the 850, and probably spins much slower. I can’t stand when companies try to save money and degrade the product. They apparently used a much cheaper motor. Yet they give it a higher number, 950, making you think you are getting an upgraded model. Buyer beware.
