Though not technically part of the OneBlade line, the comparisons are obvious and inevitable. At $35, it’s identically priced to the MSRP of the standard OneBlade, but its adjustable length comb can only be found on the $80 OneBlade Pro. That said, the Beardtrimmer is quite a bit larger and less nimble than both, and crucially, can only cut in one direction, whereas the more maneuverable OneBlades can go back and forth across your face in two directions, at least without a comb attached.
Along with a demo unit, Philips sent us a horrifying, bearded doll head inside a shattered plastic display case. Lacking a significant beard of my own, and with an insatiable desire to create internet content, I set to work with the Beardtrimmer. It struggled a bit with the dense doll hair, but I did eventually sheer most of it off. Once I was done though, I did a once-over with my personal OneBlade with no comb attached, and found that it trimmed the hairs shorter than the Beardtrimmer 3000 at its zero length setting, and was much easier to maneuver to boot.
So, as someone who spent 15 minutes alone in a bathroom shaving a doll, I continue to recommend the OneBlade without hesitation. If you can live with its three included length combs, it’s an all-around better buy at $35. If you need more length options, I’d splurge on the OneBlade Pro if you can, but the Beardtrimmer 3000's an okay alternative at the price, as long as you aren’t using it for a close-ish shave.
