Braun All-in-One 7440 review
Twelve pieces against the usual twenty-three, and it publishes more about them than anything else in this category. The battery is the part that gives.

The short version
Buy it if you want to set a length and return to it exactly. The Precision Wheel publishes 40 settings in 0.5 mm steps across 0.5-20 mm - the finest published length control in this ledger - and Braun states 100 per cent waterproof flatly rather than hedging with "showerproof". The battery is the trade: 100 published minutes against the Philips 7000's 300, with no published charge time at all.

It publishes more than anything else in the category
This is the unusual thing about the 7440 and it is why it is on this site at all. Braun publishes the full contents list piece by piece, the exact number of length settings, the step size between them, the range they cover, and a flat waterproof claim.
Most of this category publishes a piece count and a photograph. A kit that tells you 40 settings in 0.5 mm steps across 0.5-20 mm is telling you something checkable, and it is the reason it beats better-batteried kits on our kit roundup for anyone who cares about repeatable length.
The battery is the honest problem
A published 100 minutes puts it last among the kits here: the Philips Multigroom 7000 publishes 300, the 5000 publishes 168, and even the single-purpose Wahl Aqua Blade publishes 180.
The larger issue is the missing charge time. Braun publishes a five-minute quick charge on its shavers and nothing at all here, so a flat battery on a Sunday morning costs you an unknown amount of waiting. That is a genuine gap on a tool otherwise defined by how much it discloses.
The one piece of filler
A twelve-piece kit with five real heads is lean by this category's standards, and the Gillette ProGlide razor is the exception. It is a good cartridge razor. It is also the piece most likely to go unused, and it attaches an ongoing proprietary consumable to a kit whose other heads have none.
If you already shave with cartridges it is a genuine inclusion. If you have moved to a safety razor it is packaging, and you should mentally price the kit as eleven pieces.
Who should buy it
- Anyone who wants a repeatable length above all. Nothing here matches 40 published stops.
- Anyone who shaves and trims in the shower. A flat 100 per cent waterproof claim rather than a hedge.
- Anyone who wants a kit without a drawer of guards. Twelve pieces, five heads.
- Anyone who values published specifications. It is the best-disclosed product in its category.
Who should not
- Anyone who charges infrequently. Shortest runtime here and no published charge time.
- Anyone who wants a foil shaver head. The Philips 7000 has one; this has a cartridge razor instead.
- Anyone with a beard past 20 mm. The wheel stops there.
The verdict
The best-specified kit in a category that mostly refuses to specify anything, undone on one axis by a battery that is genuinely last in class. Which of those matters more is a real decision rather than a marketing one.
If you trim weekly at a length you care about, take the wheel and charge it on Sundays. If you want the thing to run for months without thinking about it, the Philips 7000 publishes three times the runtime and gives up the fine control to get there.

Our pickThe best-specified kit at any piece count
Braun All-in-One Series 7 Trimmer, 12-in-1 Kit, 7440
Twelve pieces rather than twenty-three, and it publishes more about them than anyone else here. A Precision Wheel with 40 length settings in 0.5 mm steps across 0.5-20 mm, 100 minutes of Li-Ion runtime, and 100% waterproof rather than the usual showerproof hedge. Braun also puts a Gillette ProGlide cartridge razor in the box, which is either useful or the one piece of filler depending on what you already shave with.

The arithmetic: 260 uses a year x 5 years of assumed service life = 1300 uses.
What it gets right
- 40 published length settings in 0.5 mm steps across 0.5-20 mm, the finest published resolution of any kit here
- Published 100-minute Li-Ion runtime
- 100% waterproof, stated flatly rather than as 'showerproof'
- Five heads: metal trimmer, body groomer, detail trimmer, ear and nose trimmer, and a Gillette ProGlide razor
- Braun publishes the full contents list piece by piece, which most makers do not
Flaws
- Charge time is not published anywhere on Braun's US page
- 100 minutes is a third of what the Philips 7000 publishes
- The ProGlide razor ties one piece of the kit to a proprietary cartridge you have to keep buying
- 'Lifetime ultra sharp' is a marketing phrase, not a published blade interval
The working behind the 6.7
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 8.0
- 40 published settings means you can find a length and return to it exactly (++), 100% waterproof (+), full contents list published (+), but no published charge time (-) and 100 minutes is short against the category (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 7.1
- 5 of 7 specifications a buyer would expect are published: runtimeMin, minLengthMm, maxLengthMm, settings, waterproof. Not published: chargeMin, warrantyLabel. 5 / 7 x 10 = 7.1.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled 3 September 2026 from Braun All-in-One Series 7 7440 published specifications.

Questions people actually ask
Is twelve pieces enough?
Count heads rather than pieces. This has five - metal trimmer, body groomer, detail trimmer, ear and nose trimmer, and a Gillette ProGlide razor - which is roughly what a 23-piece box gives you. The difference between 12 and 23 is mostly plastic guards. The kit roundup takes that number apart.
What is the Precision Wheel?
A dial that sets cutting length continuously rather than by swapping combs - 40 published stops in 0.5 mm steps. It is the reason to buy this kit over a better-batteried one, because a length you can return to exactly is what stops a beard drifting shorter over months.
Is the Gillette razor in the box useful?
It depends entirely on what you already shave with. If you use cartridges, it is a free razor. If you have moved to a safety razor, it is the one piece of filler in an otherwise lean kit, and it ties that piece to a proprietary cartridge you have to keep buying.
How bad is the 100-minute runtime?
It is the shortest of any kit here by a distance - the Philips 7000 publishes 300 minutes. Worse, Braun publishes no charge time for it, so you cannot work out what a flat battery costs you. For a tool used weekly it is livable; it is still the clearest figure against it.
Does it publish a blade replacement interval?
No. Braun calls the metal blade "lifetime ultra sharp", which is a phrase rather than an interval. Compare Braun's own XT5, which publishes six months - that is what a real disclosure looks like.
