Where to buy
Design and Build Quality
When it comes to the design and build quality of the Braun Series 5 5120S, it's clear they've put some thought into it. At first glance, the shaver has a sleek and modern appearance, which is great for anyone who values style in their grooming tools. The shaver's body is crafted from high-quality plastic with rubberized grip areas, making it easy to hold onto, even when your hands are wet or covered in shaving gel.
Thoughtful Ergonomics
The ergonomic design of this shaver makes it a breeze to maneuver across your face. It's shaped to fit comfortably in your hand, almost like it was custom-made just for you. However, if you have larger hands, you might find it a tad small, especially if you're used to heftier models.
Robust Construction
In terms of build quality, the 5120S feels sturdy enough to last. You don’t feel like it’s going to fall apart if you accidentally drop it. Yet, while it's durable, it’s not quite as heavy-duty as some of the high-end models out there, so treat it with a bit of care for longevity.
Attention to Detail
One of the neat elements is the precision trimmer that pops up smoothly from the back. It’s handy for those tricky areas like sideburns or the back of your neck. But, if you're looking for fine detailing, a dedicated trimmer might still be your best friend.
The Braun Series 5 5120S offers a mix of solid design and functional build, with just a pinch of luxury. While it's not the most rugged choice on the market, it balances practicality with a touch of elegance, making it a solid contender for your grooming kit.

Features and Technology
The Braun Series 5 5120S packs a punch with some nifty features and technology that can make your shaving routine smoother and more efficient. Let's break it down.
At the core of this shaver is the Autosense Technology, which is like having a mind reader on board. It adjusts the power based on the density of your beard, ensuring a consistent and comfortable shave. So, whether you're dealing with a light stubble or a full-grown beard, this little guy adapts accordingly without you having to lift a finger. How cool is that?
The shaver also boasts a 3-Flex Head design that promises to follow the contours of your face. This means fewer missed spots and a closer shave with each pass. It’s like a dance partner that never steps on your toes! However, some users might find that it doesn’t glide as smoothly over very rough or uneven skin, so a bit of patience might be needed for those areas.
Another neat feature is its Wet & Dry capability. You can use it with shaving gel or foam, and yes, it is shower-friendly! Whether you’re in a rush or want to pamper yourself, the choice is yours. However, keep in mind, while the wet option is great for sensitive skin, it might not be quite as efficient as the dry shave for some.
The Braun Series 5 5120S doesn’t stop there. It also includes a precision trimmer that’s perfect for grooming sideburns or mustaches. Although it might not replace your dedicated trimmer, it’s a handy feature for quick touch-ups.
Lastly, let's talk about its waterproof design. You can rinse it under running water, making cleaning a breeze. Though, if you’re someone who prefers a deep clean, you might find the standard rinse a bit lacking.
In a nutshell, the Braun Series 5 5120S rolls out a red carpet of features that cater to both flexibility and convenience, making it a solid choice for most folks looking for a reliable shave. But hey, nothing's perfect, right? A few quirks here and there, but overall, not a bad gadget to have in your grooming arsenal!

Performance and Efficiency
When it comes to performance and efficiency, the Braun Series 5 5120S doesn't mess around. First off, its AutoSensing motor is a real powerhouse. This feature automatically adjusts the motor's power to match the density of your beard, which means you get a consistent shave regardless of how stubborn your facial hair might be. Imagine driving a car that automatically switches gears for the best performance. That's what this shaver does for your face.
The shaver heads boast a Triple Action Cutting System, featuring two SensoFoil blades and an integrated middle trimmer. This setup efficiently slices through both long and short hairs, providing a close shave without multiple passes. It's like a Swiss army knife for your face, cutting through various beard terrains with minimal effort.
On the efficiency front, you’ll find that the built-in precision trimmer is quite handy for detailing sideburns and trimming around those tricky areas like under the nose. Though it's not as robust as a dedicated trimmer, it gets the job done well enough for those quick touch-ups.
Now, a small hiccup: if you're expecting a whisper-quiet experience, you'll notice a bit of noise. While it's not a dealbreaker, it might be a slight surprise if you're used to quieter models.
Overall, the Braun Series 5 5120S offers a strong performance that balances power and precision, making your shaving experience faster and more efficient. Whether you're in a morning rush or have time to spare, this shaver delivers reliable results.
Battery Life and Charging
Battery Life and Charging can make or break your shaving experience, especially when you're running late and need a quick touch-up. The Braun Series 5 5120S promises a decent performance in this department, but let's see how it holds up in reality.
First off, the battery life is pretty strong. You get about 50 minutes of shaving time from a full charge. That's enough for multiple shaves, so you won't be tethered to an outlet every day. However, if you’re someone who shaves daily, you might find yourself charging it more often than you’d like.
Charging is quick and easy, thanks to the fast charge feature. Got only a few minutes to spare? No worries. In just 5 minutes, you can get enough juice for a quick shave—perfect for those "Oops, I forgot to charge it!" moments. But remember, this quick charge won’t last for a long session, so plan accordingly.
The shaver uses a standard charging cord, which means you don't have to deal with docking stations or complicated setups. Just plug it in and you’re good to go. It's straightforward, but some might miss the convenience of a fancy charging stand or a USB option for travel. One minor hiccup? There’s no battery level indicator, so you might be caught off guard with a suddenly dead shaver. Think of it like a car without a fuel gauge—you’ve got to keep track of how long you’ve been using it.
In summary, the Braun Series 5 5120S offers good battery life and handy quick charging, but the absence of a battery indicator can be a bit of a blind spot. It's not a deal-breaker, but something to keep in mind if you're someone who relies heavily on knowing exactly how much charge is left.

User Experience and Comfort
Using the Braun Series 5 5120S is like having a trusty companion by your side every morning. Comfort is front and center with this shaver, thanks to its thoughtful ergonomics. The handle fits snugly in your hand, making sure you have a firm grip even with wet hands. This is especially handy during those quick in-shower shaves.
The FlexMotionTec is a game-changer. The shaver head moves around like a dance, easily adapting to the contours of your face. It means you're less likely to have those annoying missed patches. Nobody wants to show up at work looking half-shaved!
But, it's not all smooth sailing. Some users find the noise level a bit distracting. It’s not a dealbreaker, but if you're half asleep in the morning, it might wake you up faster than your coffee.
Another perk is the SensoFoil blades. They're designed to be gentle, which means less irritation for those with sensitive skin. You can say goodbye to that dreaded post-shave rash. However, if you have a thicker beard, you might notice it takes a bit longer to get that perfectly smooth finish.
Switching from dry to wet shaving is seamless, giving you lots of flexibility in your routine. Whether you prefer shaving cream or going dry, this shaver has your back. It’s like having your cake and eating it too.
The overall user experience with the Braun Series 5 is quite pleasant, despite the few minor hiccups. It’s like a reliable friend who mostly knows how to keep things smooth and comfortable.
What's in the Box
When you crack open the box of the Braun Series 5 5120S, it feels a bit like getting a new gadget as a gift—there's something exciting about seeing everything neatly packed and ready to be used. So, what's all packed into this little box of shaving wonders?
- The Shaver Itself: Of course, the star of the show is the sleek and ergonomic shaver. It's well-built and feels solid in your hand, so no worries about it slipping mid-shave.
- Charging Cord: You’ll find a compact charging cord, which is quite handy for travel. It’s not too bulky, but it might be easy to misplace if you're not mindful.
- Protective Cap: A simple yet useful addition, the protective cap keeps the shaver head safe from damage when you're not using it. It's like a little helmet for your shaver.
- Cleaning Brush: A small brush is included to help you keep the shaver in tip-top shape. It’s not fancy, but it gets the job done for those quick clean-ups.
- User Manual: The manual is there to guide you through the setup and provide tips on getting the best shave. While mostly straightforward, some might find it a bit too basic.
One thing you might notice is the absence of a travel pouch, which would have been a welcome addition for those jet-setting or just wanting to keep things organized in the bathroom. But hey, not a deal-breaker if you’re careful with your stuff. Overall, the Braun Series 5 5120S comes with all the essentials to get you started on the path to a smoother shave.

Competitor Comparison
When sizing up the Braun Series 5 5120S against its competition, you start to see some interesting differences and similarities. Let's break it down to give you a better picture of where this shaver stands.
Philips Norelco 3800
The Philips Norelco 3800 is a noteworthy contender in this price range. It uses a rotary system which some folks find better for maneuvering around facial contours. While the Series 5 uses foil technology, the Norelco's rotary heads might give a smoother experience for those with less dense facial hair. However, it doesn't quite match the precision of the Braun's cutting system when handling denser or coarser beards.
Panasonic Arc3
The Panasonic Arc3 is another option that often gets compared to the Braun Series 5. With its strong linear motor, it provides a close shave but lacks some of the adaptive shaving technology that Braun offers. The Arc3 also typically comes at a lower price point but without some of the premium build and features like Braun’s waterproof design.
Remington F5-5800
For those on a budget, the Remington F5-5800 is a solid choice. It's a no-frills foil shaver that's easy on the wallet. However, compared to the Series 5, it doesn't have the sleek, modern design or the same level of comfort and performance. The Remington is great for basic needs but falls short on the advanced features and technology spectrum.
So, what's the takeaway? If you're looking for a shaver that balances advanced technology with comfort and ease of use, the Braun Series 5 5120S is a strong contender. However, if you're more price-sensitive or prefer different shaving mechanisms, there are viable alternatives that might better suit your needs.
Conclusion
After taking a good look at this shaver, it's clear that the Braun Series 5 5120S offers a solid blend of comfort and efficiency for everyday grooming. Its sleek design and intuitive features make it a reliable choice for those who value straightforward usability without compromising on performance.
While it delivers a close shave and maintains skin comfort, its lack of some advanced features found in higher-end models might leave tech enthusiasts wanting more. But hey, not everyone needs all the bells and whistles! If you’re searching for a shaver that balances well between functionality and simplicity, this one hits the mark.
Battery life is commendable, though it could be improved to cater to those constantly on the move. However, with a reasonable charging time, it won't keep you waiting too long. The ergonomic design ensures a comfortable grip, making it easy to maneuver around those tricky spots.
In comparison to its competitors, the Braun Series 5 5120S holds its ground by offering a dependable shaving experience without burning a hole in your pocket. It's not the flashiest scooter on the block, but it gets you where you need to go with minimal fuss. All in all, if you're after a mid-range shaver that does its job with minimal hassle, this one fits the bill quite nicely.
FAQ
Q: Can I use the Braun Series 5 5120S in the shower?
Yes, this shaver is 100% waterproof, meaning you can comfortably use it in the shower without worry. It's great for those rushed mornings when multitasking is key. Just remember, like all waterproof devices, make sure to dry it off properly after use to prolong its life.
Q: Does it work well on a thick beard?
Absolutely! The shaver's AutoSensing Motor technology adapts to the density of your beard, which makes it effective even on thicker growth. However, if you've got a particularly unruly beard, you might need a couple of passes in some areas, but it gets the job done.
Q: How often should I replace the shaving head?
You should replace the shaving head every 18 months to keep it at peak performance. Think of it like changing the oil in your car—regular maintenance keeps everything running smoothly.
Q: Is it easy to clean?
Cleaning is a breeze! Just rinse the shaver head under running water. The design is simple, so there's no need to fuss around with small parts. However, it's always good to give it a more thorough clean every so often by removing the shaving head and gently cleaning it.
Q: What's the battery life like?
On a full charge, you can expect about 50 minutes of shaving, which is plenty for several uses. If you forget to charge it and you're in a rush, a quick 5-minute charge provides enough juice for a single shave. Just be careful not to rely on that quick charge too often, as frequent full discharges followed by a full charge keep the battery healthy.
Q: Can I use shaving cream or gel with it?
Yes, you can! This shaver is designed for both wet and dry use, so feel free to lather up with your favorite cream or gel for an extra smooth shave. Just make sure to rinse it off well afterward.
