Braun Series 3 Electric Shaver 300BT (Grey) with Beard Trimmer Attachment
Product description
The essentials
Braun’s Series 3 Electric Shaver 300BT is a dry electric shaver for men, aimed at a close, straightforward shave without turning your routine into a project. On paper, it leans into what most people actually want day to day: less faff, a comfortable fit to the face, and the ability to handle short stubble and a bit of longer hair.
The setup here is built around foil shaving plus a trimmer: the shaver uses 2 Braun foil shaving elements and 1 centre trimmer to help with longer hairs that a basic foil head might miss. It also includes 3 flexible blades designed to adapt to your contours, which is the sort of detail that can make shaving feel easier on areas that are a bit awkward.
What you’ll notice during shaving

Where this model makes sense is in the “close and clean” goal, paired with flexibility. The 3 flexible blades are designed to move with your face, so you’re less likely to feel like you’re getting straight-line results only. That matters especially around the jawline and along the side of the face.
There’s also a thin shaving head meant to help in hard-to-reach areas, plus a beard trimmer attachment for sideburns and a moustache. That combination is handy if you’re not trying to do full beard sculpting, but you still want clean edges and even growth to be under control.
One small limitation to keep in mind: it’s a dry shaver. If you strongly prefer a wet shave with foam and water, this isn’t built for that routine, and you may find it less satisfying than models aimed squarely at wet shaving.
Key features that affect everyday convenience



The battery life is specified as up to 30 minutes, with a 5-minute quick charge for one shave. That’s the kind of practical detail that tends to matter when you’re running late or travelling.
It’s also described as waterproof and head washable. That’s a useful baseline for hygiene and for keeping the shaving head from getting clogged, especially if you tend to shave regularly.
Attachments, charging, and compatibility considerations
In terms of the beard side of things, the package includes a Beard Trimmer Head, plus +5 combs. That suggests more than a one-length trim, though the exact comb lengths aren’t provided here—so it’s worth checking those details if you have a specific stubble length in mind.

Charging is via a 2-pin plug charger, intended for a UK bathroom 2-pin socket. If your socket is a 3-pin type, the product notes you’ll need an EU to UK adapter (not included). That’s worth factoring in before purchase, because it can be the difference between “works straight away” and “quick trip to buy an adapter”.
Who it suits (and who might want to look elsewhere)
It’s a solid match if you want a reliable men’s foil shaver for regular dry shaving, with enough flexibility to handle uneven growth without excessive passes. If your routine includes tidying sideburns or a moustache, the included beard trimmer attachment and combs fit the idea of quick grooming rather than detailed beard work.
It may not be the best choice if you’re specifically looking for a wet-and-dry system, or if you’re expecting the sort of precision you’d normally associate with a dedicated multi-length beard trimmer. This is more about a clean daily shave first, with trimming support as an add-on.

Is it worth it?
Worth buying if you want an everyday dry shaver that’s built around foil comfort, flexible blade action, and a simple trim attachment for sideburns and moustache. It’s the kind of kit that typically suits people who shave often and want results that feel close without too much effort.

Better avoided if you need a wet shave setup, or if you already know you’ll be disappointed by the dry-only approach. Also, if you’re unlikely to have the right adapter for a 3-pin socket, factor that in—because the charger is described as 2-pin.
