Review on 🪒 High-Quality SH30 Replacement Heads for Philips Norelco Shaver Series 3000, 2000, 1000, and S738 - Durable Sharp Blade, Comfortcut Replacement Blades, Razor Blades for Philips Norelco S1560 by David Gonzalez

01/19/2021 UPDATE: After 3 months of use I noticed that it is pulling out hairs that have grown back after a few days (maybe >1mm). If you shave every day, this shouldn't be a problem. But if you shave every few days after your 5 o'clock shadows have grown back a bit, it can be a painful experience. downgraded to 4 stars. Tuokiy received the OEM mark. It fits and works great in my old Hattaker razor. The Hattaker had 9 Dual Blades per head. Tuokia has 9 individual blades slightly wider. So far there have been no problems with hair pulling or skin cutting. I will update this review if I notice any issues.
