I find all equally good in that regard, although shaving a one-week beard would be really on the limit. To me, the regular Series 9 is a bit gentler while the Pro/PRO+ Series 9 feels a bit more powerful. Price and value for money aside, the Series 9 is currently Braun’s best shaver.
Braun’s Series 9 clean-and-charge base uses the same cartridges as the Series 7 base (and those of all other braun shavers) and is functionally identical. Replacement cartridges last about three months and cost about $25 for a four-pack. Replacement foils are considerably more expensive for the Series 9; they currently run about $50, compared with about $30 to $40 for the Series 7. Two of the reasons you may prefer using an electric razor on your face instead of a manual razor are convenience (being able to shave anytime, anywhere without water) and safety (no risk of nicks).
But getting back to the 11B/10B, it’s a very basic single foil and single blade set that should be replaced every 18 months according to Braun. As you can tell from the comparison table above, some models like the 190s are cordless-only shavers, while the 170s and 130s models are corded-only. But considering the above-mentioned limitations, along with the fact that some Series 1 models cost almost as much as the (better) Series 3, make the Series 1 a rather difficult shaver to recommend. Most dry-only variations are however waterproof and you’ll still be able to safely clean them with water. As a rule of thumb, the higher the number of a series, the better, more capable and more advanced the shavers belonging to that series are — e.g. a Series 8 razor is better than a Series 3.
Shaving with the Braun Series 9 Pro+ still takes me about three minutes (sometimes less, if I don’t have much stubble to power through), but where it really shines is the closeness of the shave. Most of the new features, including the pre-shave ProComfort head, focus on more effectively lifting facial hair away from your skin allowing for a closer, smoother shave. “Waterproof” means different things to different people, but when you see it on a product’s packaging, it likely braun electric shavers means that the device is 100% waterproof. If you see only “wet/dry usage” listed, then it is probably merely rinsable and suitable for use with a shaving cream. At the very least, your device’s head should be able to rinse cleanly under running water, in order to mitigate bacterial accumulation and hair buildup. It’s a bonus, though, if the tool can handle shaving in the shower (meaning, it’s fully waterproof) or being used along with shaving cream or a similar product.
Rotary and foil shavers both provide an exceptional shave, but each has its own characteristics. If you have longer and thicker hair or like to go days in between shaves (two or even three days, for some guys), then a rotary razor is best. It’s also good for those with coarser beard hair, thanks to the circular heads that easily maneuver tougher hair patterns seamlessly. Foil shavers add a precise method of hair removal that’s especially ideal if you have fine to medium strands. My shaver-reticent partner has started using it too, probably because I’m the designated packer of grooming products whenever we travel, and he’s stuck with what I present him.
