Short answer
A OneBlade trims to just above the skin. It's gentler, great for stubble styles and razor bumps, but never baby-smooth. A foil or rotary shaver like the Braun Series 7 gets you clean-shaven. If you get bumps from close shaving, start with a OneBlade; if you want smooth, get a shaver.

The details that decide it
Why bumps happen
Curly hair that's cut below the surface can grow back into the skin. A OneBlade leaves it at the surface. A close shaver can't avoid going lower.
Lengths and styling
The OneBlade Pro 360 has a precision comb with 14 settings from 0.4 to 10 mm, so the same tool keeps a stubble length exact and edges the lines. A foil shaver like the Braun Series 7 has one job: taking hair down to the skin.
Battery and charging
The OneBlade runs about 90 minutes on a one-hour USB charge. The Braun Series 7 runs on a Li-ion battery that lasts longest in Gentle mode and is fully waterproof.
Running cost
Philips rates a OneBlade blade for up to four months. The Series 7 head lasts about 18 months. The cost table below shows how the blade schedule adds up over five years.
Using both
If you alternate between stubble weeks and clean-shaven weeks, the OneBlade covers the stubble and the edges and a shaver covers the clean days. That's two tools, but neither is doing a job it's bad at.
Who should skip both
If your skin reacts to anything that cuts close and you still need to be clean-shaven for work, talk to a dermatologist about razor bumps (pseudofolliculitis barbae). No shaver choice fixes that on its own.

FAQ
Is OneBlade better than an electric shaver?
For bumps and stubble, yes; for smoothness, no.
Can OneBlade replace a shaver?
If you're happy with very short stubble, yes.
How long does a OneBlade blade last?
Philips rates it for up to four months. Replacement blades are the main running cost of a OneBlade.
Can the OneBlade Pro 360 be used on the body?
Yes. The kit includes a body blade with a click-on comb and skin guard.
Is the Braun Series 7 good for razor bumps?
It can help, and its Gentle mode is useful on irritated days. But any close shave cuts curly hair below the surface, which is what causes bumps. If bumps are your main problem, start with the OneBlade.
