The reminder is on the machine
Philips shavers light an icon when the heads are due. That is more reliable than counting months, and it is part of the shaver rather than the packaging. Five of the eight shavers on this site publish a replacement interval; the icon is on the Philips ones.
Buy on the code, never on the range name
The SH30 heads are stated for S1XXX, S3XXX and S54XX. The SH71 for S77XX and S55XX. Those patterns are checkable in one glance against the code on your shaver — and they expose a trap: a shaver sold as “Series 3000X”, model X3053, matches none of them.
A range name is marketing. A code pattern is a specification. Where the two disagree, as they do on the 3000X, the pattern is right.
The reset, one line on the listing
After fitting new heads, hold the power button for more than seven seconds to clear the reminder. Without it the icon keeps signaling and the new heads get blamed.
What it costs, and why it decides the purchase
Replacement heads on the shaver heads shelf run from $25 to $34, and the arithmetic only closes where both halves are published. On this site that is one pair: the S5465 at $120 with SH30 heads at $29 — just under a quarter of the machine, every two years.
The S3145 and the S7887 take the same two head references and publish no price of their own, so for those the running cost is the readable half. Do that sum before choosing between two shavers, not after.
Beware the near-copies — and know what a genuine wide fit looks like
Listings for “compatible” heads can fit without being the specified part, and the reference code is what distinguishes them.
What that does not mean is that a long compatibility list is a warning sign. The Norelco Multi-Fit bodygroom head at $33 is the clearest case on the site: it publishes about forty named model numbers across Bodygroom, AXE, Satinelle and even two Remington references, and a named model list is the one form of answer that is definitive. Compare that with a third-party head sold for “all Series 3000” — a family name answers the question probabilistically, a model list answers it.
So the test is not how many models a part claims, it is whether it names them. And on the Norelco page, check the description as well as the bullets: the two lists on that page do not quite agree with each other.

What people ask about this
How do I find my shaver's code?
It is printed on the body of the shaver and in the manual — something like S3145/00 or S7887/35. Philips publishes head compatibility as code patterns (S1XXX, S3XXX, S54XX for the SH30; S77XX and S55XX for the SH71), and matching the pattern is the check. In the United States the same shavers are sold under the Norelco name, and the code on the body is what carries across.
My new heads still show the reminder — are they faulty?
Almost certainly not. On Philips shavers, the reminder is cleared by holding the power button for more than seven seconds. It is one line in the listing and it is the step most often missed.
Does every shaver have a scheduled head?
No — five of the eight here publish a blade life: the four Philips rotaries at two years, and the Panasonic ES-LV67. The Braun 3040s and two of the Panasonics publish no interval at all, which does not mean the head lasts forever, only that you will be judging it by how it cuts.
