I’m sorry to hear that. When I did shave, I would use the Norelco Lift and Cut and I would send it to have the proper blade adjusted. It worked well for me. Everything it seems is made like dreck nowadays. I think they used to make these shavers in Europe, but now they make them in China. Please note that I am not an expert on these things, but am just relaying information from the Kosher Shavers people who hold like R’Dovid Feinstein and R’ Blumenkrantz, zt’l. There may be other poskim who have different opinions on this.
I came across this website selling a kosher shaver with the hechsher of R’ Chaim Katz and others : http://koshershave.com/.How good it works, I don’t know, but maybe someone on the CR knows.
