Review on 🔧 Enhanced Phillips Norelco SH90/72 Replacement Heads for Series 9000 (Replaces SH90/62) by Laurel Rohr

I bought these to replace the original blades and guards that came with the original razor. Although the old razor blades and guards made the expected noise level, they became dull with use and had to be replaced. After new blades and shields were installed, the razor sounded normal when turned on, but made an awful vibrating/grinding noise even with the slightest pressure. After replacing the old blades the horrible noise was gone and the razor worked perfectly. just boring. Looking at the replacements, it's obvious that they aren't the same. The "head" snaps well on the old device, but the performance shows that they are not compatible at all. I actually spent my money on two replacement sets, both made the same grinding noise. Considering how expensive these replacement parts are, you'll save a lot more money by simply buying a brand new razor.
