What's the difference between Philips razor blade models?

1, 2, 3 and 4 cutter heads are the same, 15 cutter head, single-layer blade. Eliminating products does not reflect the advantages of Philips.

Cutter heads No.5 and No.6 are the same, 15 cutterhead with double blades. Low-end products, good quality and low price. The effect of "lifting beard" is obvious, but it is only suitable for young people with soft beards.

No.7 and No.8 cutterhead are the same, No.9 cutterhead has double blades. Mid-range products, value for money. The shaving effect is obvious.

No.9 cutterhead is double ring, outer ring 12 cutterhead, double-layer blade, inner ring 6 cutterhead and single-layer blade. Shave quickly. Although it is a high-end product, the low-priced product 9080 in its double-headed series is the most valuable in my opinion.
