I used a Norelco Rotary Razor for 4 decades. Bought new shaver heads every 10 years. It finally failed and I bought a new one that was about the same price. I forgot that prices of old stuff don't mean the same today. Well some things get better cheaper. But in this case the same price new one (different brand) was a piece of junk.
So I bought the best I could find this time. Why not? I probably have 20 more years of shaving every couple days.
