The dual-sided blade is designed to cut more precisely than a comb and we find they last about 6 weeks to 3 months before needing to be replaced.

The precision dial on the single comb is arguably the Hatteker's party trick, as it allows for a rapid change in hair length without the faff of continuously changing heads.In use, it produced excellent, effortless results, perhaps thanks to Braun’s AutoSensing technology, which adjusts the trimmer’s power according to your beard’s thickness. Indeed, we found you can approach from any direction, without precise positioning, and it cuts smoothly and evenly every time with zero snagging.

Battery performance is solid too, with Philips promising a full two hours of usage from an hour-long charge. If you want to use the combs, however, then these simply clip on over the top of the beard trimmer head. In truth, that’s more of a fun feature than an essential one, but the battery life display is genuinely useful, showing you how many minutes of cutting time you have left. Some masquerade as shavers-cum-trimmers; others are advertised as body stylers, for tidying up everything from facial hair to delicate body areas. And if you want to get an even closer cut or create more intricate lines, for an altogether more professional look, there’s an additional detail-trimmer attachment.Indeed, though some models have just a main trimmer and pop-up detail trimmer, others come with a range of swap-out attachments including foil shavers and nose-hair trimmers.

The BT5260 offers the same features as the BT5240 and also includes a detail trimmer attachment for even more versatility. This allows us and our advertising providers to show adverts more relevant to you, limit how often you see an advert and build a profile of your interests. The main selling point here is the absence of razor burn: if you’ve found other trimmers leave your face a fiery red, you will find the OneBlade considerably more gentle.
