Review on 🪒 Philips SH98/70 Replacement NanoTech Precision Blade Shaving Heads for Series 9000 Prestige: Highly Effective Grooming Solution by Jason Nelsen

I used this replacement for my SH90 shaving head and it really reduces friction. However, there is something they did that prevents me from giving them five stars. On the SH90 they are slotted on the inner ring of the head and on the SH98 they are back to the holes. I don't know why they did it. The slits didn't cause the irritation I had with my head. It was metal. The slits were in fact much better at accommodating the longer hair, so going back to the holes doesn't do as well. I've found that if I don't shave for more than a few days I have to use an extra beard trimmer to get rid of them first. This significantly increases the shaving time. I tried to write a review on their website but didn't have the opportunity. So I hope they read the reviews on this site and correct this odd decision.
