Braun 3040si review
Two Braun foils either side of a middle trimmer, three flexing blades, a MicroComb that Braun states catches more hair per stroke, a body it states is 100% waterproof, and forty-five minutes of runtime with a five-minute quick charge.
Where it leaves us An entry Braun that publishes what it is: three flexing blades, forty-five minutes, waterproof, made in Germany. Nothing is listed for it on amazon.com.
Two foils either side of a middle trimmer, on three blades that flex to follow the face. Braun calls the middle element MicroComb and states it catches more hair per stroke than the Series 3 — a comparison it names, tested on three-day beards.
The body is 100% waterproof for wet or dry use, with an integrated precision trimmer for edges and a narrow head for under the nose. Up to forty-five minutes of runtime, and a five-minute quick charge for a single shave.
Braun also states that it is made in Germany, which is a fact about the product rather than a claim about its performance, and one that essentially no other listing in this category volunteers.
One thing to settle before ordering: this reference carries no live offer on amazon.com at the time of writing, which is why the table above has no indicative price.
It is also the only shaver on this shelf that is not a Panasonic, and the comparison runs along a single line: Braun counts foils and flexing blades, Panasonic counts cutting actions per minute — 39,000 on one model, 70,000 on another. Forty-five minutes is the shortest runtime of the four, and the five-minute quick charge for a single shave is the only figure of its kind here. Against the two Panasonics that can be ordered today, at $120 and $185, this page has no price to set beside them.

What people ask about this
What is the MicroComb?
Braun's name for the middle trimmer between the two foils. The company states it catches more hair per stroke, compared with the Series 3 and tested on three-day beards — the comparison and the conditions are both given, which is more than most footnoted claims offer.
Why is there no price on this page?
Because there is no live offer on amazon.com for this reference at the time of writing, so there is nothing to read an indicative figure from. The button runs a search instead, and the figure at the top of the page appears when an offer does.

3 blades, 30° nano-edged · linear motor 39,000/min · beard sensor · 8-way head
Three Japanese stainless blades ground at 30 degrees, a linear motor running 39,000 cutting actions a minute, a beard density sensor, a head flexing in eight directions, plus a shaving-foam mode, a travel lock and a three-minute quick charge.
Best for: A dense or uneven beard, shaved wet with foam.
5 blades · linear motor 70,000/min · 16D flex head · beard sensor
Five blades, a linear motor at 70,000 cutting actions a minute, and a head that moves in sixteen independent directions. Panasonic states the steel blades shave as on the first day for five years, tested against artificially aged units.
Best for: A thick beard shaved daily, where the number of passes is the actual complaint.
A three-blade foil shaver with arc-shaped foils shaped for under the chin, a pop-up trimmer carrying thirty blades of its own, an hour to charge for fifty-four minutes of use, and a head that rinses under running water.
Best for: A daily dry or wet shave, with the head rinsed at the tap afterwards.
