Quick questions

Are all heads in one Series interchangeable?

No. Some Series names cover multiple generations. Always check the full handle model or original cassette code.

Will every user notice the same change?

No. Wear varies with usage, hair type, brushing or shaving technique, cleaning and storage.

Are the replacement periods exact deadlines?

No. They are manufacturer guidance. Replace sooner if the head is damaged, uncomfortable or visibly worn.
