SweetLF SWS7105 Review: a cheap rotary shaver that actually holds its own

I picked up this SweetLF electric razor mainly out of curiosity and because I was tired of dropping big money on Braun and Philips. My usual setup is a mid-range Braun foil shaver for the face and a cartridge razor when I want a really close shave. So I went into this test thinking, “Alright, this is a backup or travel shaver at best.” I used it almost daily for a few weeks on my face, and a couple of times on my head, to see what it was actually capable of.

The first thing I noticed was the price-to-performance gap compared to the big brands. For what it costs, it doesn’t feel like a toy, but it also doesn’t scream premium. The plastic body looks a bit cheap at first glance, but in the hand it’s not flimsy. I treated it like I normally do with shavers: tossed it in a bag, used it in the bathroom with wet hands, rinsed it under the tap. No babying it just because it’s budget.

In terms of shaving, I went in with a couple of different situations: a one-day stubble, a two-to-three-day growth, and a lazy weekend where I left it almost to four days. I also tried it both dry and with a quick rinse and a bit of foam, just to see how the waterproof claim and wet/dry marketing translated into real use. I also used the pop-up trimmer for sideburns and to tidy the neckline, which is usually where cheap shavers fall apart.

Overall, it’s not perfect and it’s not magic, but it gets the job done better than I expected. If you’re used to a proper wet shave with a blade, you won’t get that glass-smooth feel. But as a daily or every-other-day electric option that’s easy to charge and easy to clean, it’s pretty solid. The main surprise for me was the battery life and how comfortable it was on the skin, especially for the price bracket it sits in.

On value, this SweetLF shaver is hard to complain about. You’re paying a fraction of what a big-brand Braun or Philips rotary would cost, and you’re getting maybe 70–80% of the experience in terms of comfort and performance. If you’re on a budget, retired, or just don’t care about having the “top brand” logo in your bathroom, this is a sensible way to stay clean-shaven without draining your wallet.

When you factor in the battery life, the waterproof design, and the ability to use it both wet and dry, it covers a lot of use cases for the price. Add the cheap replacement heads and you’ve got a shaver that you can realistically run for a few years without spending much extra. It’s especially good value if you want a second shaver for travel, the gym, or to leave at a partner’s or relative’s place. You get something that works, holds a charge for weeks, and you won’t panic if it gets lost or damaged because it didn’t cost a fortune.

Where the value is less clear is if you’re already happy with a high-end shaver and are thinking about “upgrading” to this. In that scenario, it’s more of a side-grade or even a downgrade in terms of closeness and build feel. You’d be doing it purely to save money or to have a backup. Also, if you only shave once every four or five days and want a super close result each time, you might be better off sticking to a decent blade razor or a more powerful electric, even if it costs more upfront.

Overall, I’d say the value is strong for everyday, practical users: people who want something reliable, easy to charge, gentle on the skin, and cheap to replace. If you’re picky about premium materials and ultra-close shaves, you’ll see the limits. But as a no-nonsense tool that gets the job done for a low cost, it’s hard to argue with what you’re getting here.

Design-wise, the SweetLF SWS7105 is clearly built to hit a price point. The sky blue colour is a bit flashy, and the plastic housing doesn’t exactly scream premium. When I first unboxed it, my honest reaction was: “This looks cheaper than my Braun.” But once I actually held it and started using it, my opinion softened a bit. The shape fits nicely in the hand, and the curves on the body give you a decent grip even with damp fingers. It’s not rubberised all over, but the contours do help keep it from slipping.

The three rotary heads are mounted on a floating plate that has a bit of flex in all directions. It’s not as refined as some big-brand 3D head systems, but it does follow the face contours reasonably well. Around the jawline and chin, I didn’t have to contort my wrist too much to keep the heads in contact with the skin. On the neck, you still need to go over spots a couple of times, but that’s pretty standard with rotary shavers in general. The pop-up trimmer sits at the back and flips up easily with a thumb. It’s not the most solid mechanism I’ve used, and I can see how someone heavy-handed could snap it if they force it, but if you’re careful it works.

The LED battery display is placed on the front and is easy to see while shaving. It’s not super bright, but in normal bathroom lighting it’s readable. There’s a single power button, no extra modes, no gimmick features. Honestly, I prefer that to shavers that have three different “turbo” and “sensitive” settings that you never actually use. One button, on/off, and a clear percentage readout is enough. The USB-C charging port is slightly recessed and, like one reviewer mentioned, a bit picky with cables. My random phone cables didn’t always click in as nicely, so I mostly used the supplied charger to avoid fighting with it.

In short, the design is functional, not pretty. It looks like a budget shaver but handles better than it looks. If you can live with a slightly cheap aesthetic and treat the moving plastic parts (like the trimmer) with a bit of care, it’s fine. If you want something that feels like a metal tool, this isn’t it.

The battery life on this thing is honestly one of its best features. The spec says around 120 minutes, and that lines up pretty well with what I saw. I charged it fully once, then used it for quick daily shaves (around 5–7 minutes each). After about three weeks, I still had charge left. The percentage on the LED dropped slowly and predictably. I never had that “oh, it suddenly died mid-shave” problem that I’ve had with some older electrics.

The 1-hour fast charge claim is also roughly accurate. From nearly empty to full took just under an hour on the supplied charger. I also tested the “emergency top-up” idea: plugged it in for about five minutes when it was very low, and it gave me enough power for a full face shave without slowing down. For travel, this is very practical. You can easily charge it the night before a trip and forget about it for a couple of weeks if you’re only shaving once a day.

Charging is via USB, which is nice, but there is a small catch. The included cable and adapter work perfectly, but not every random USB-C cable I own felt as snug in the port. It’s a slightly tighter fit than my phone, so I ended up just leaving the included cable with it. Not a huge issue, but if you were hoping to use absolutely any cable lying around, you might have to test a couple to see which ones seat properly.

Compared to branded shavers I’ve used, the battery performance is right up there, if not better in some cases, especially at this price point. There’s no removable battery, so long-term you’re stuck with what’s inside, but that’s standard for most modern shavers. For now, though, the combination of long life, clear percentage readout, and fast charging makes the battery system one of the main reasons I’d recommend it as a travel or backup shaver.

On comfort, this razor is actually where SweetLF did a decent job. I tried it both on my own skin and also lent it to an older relative who usually complains about irritation from blades. The feedback from both of us was similar: it’s pretty gentle. You don’t get that aggressive scraping feel that some cheaper electrics give when they’re underpowered or badly designed. Even going over the same spot multiple times on the neck, I didn’t end up with red patches, which I often do with foil shavers.

On a one-day stubble, the heads glide quite smoothly, especially if you do small circular motions like you’re supposed to with rotary shavers. On two-to-three-day growth, you do feel a bit more resistance, and you need more passes, but it still doesn’t tug badly. It’s not as soft-feeling as a high-end Philips, but considering the price gap, I didn’t feel like I was punishing my skin. My older relative, who has thinner, more fragile skin, found it comfortable enough for daily use and preferred it to a wet razor because there was no fear of cuts.

Using it wet with a bit of foam makes it even more comfortable. I tried a quick wet shave in the shower, just with some gel, and it glided better and left the skin feeling less dry afterwards. The waterproofing seems legit; I rinsed the heads under running water after several shaves and didn’t notice any weird noises or issues afterwards. The body doesn’t feel slippery even when wet, which helps if you’re using it in a steamy bathroom or in the shower.

If your main concern is comfort over ultimate closeness, this shaver does pretty well. It’s especially suited for people with sensitive or mature skin, or anyone who’s nervous about blades. If you’re used to a super-close razor shave and push hard trying to chase that same result, you might irritate the skin a bit, but if you let the razor do its thing and accept that “very decent but not glass-smooth” is the goal, it’s a comfortable daily tool.

Durability is where the low price shows a bit more. After a few weeks of use, nothing broke on mine, and there were no rattles or weird noises. The head still snaps on firmly, the pop-up trimmer still works, and the motor runs at a steady speed. I rinsed it under the tap after most uses, sometimes with warm soapy water, and there are no signs of water getting where it shouldn’t. So in the short term, it holds up fine to normal use and basic cleaning.

That said, the plastic body and especially the trimmer mechanism don’t give the same confidence as a more expensive metal-heavy shaver. If you’re rough with your gear, drop things often, or tend to throw items around in a bag without protection, I wouldn’t be shocked if the casing picked up cracks or the trimmer got damaged over time. One Amazon reviewer mentioned breaking the trimmer while putting it back together, and I can see how that might happen if you push it the wrong way. This isn’t a tank; it’s more like a decent plastic tool you should treat with some care.

The blades and heads seem to hold up reasonably well. After a few weeks of daily use, they still cut cleanly with no obvious dullness. Replacement heads are available and not overly expensive, which is important if you plan to keep it for a couple of years. Based on the user reviews and my own feel, changing them roughly once a year for regular use seems fair. If you keep the heads clean and don’t let hair and gunk build up, you’ll probably stretch their life a bit longer.

In short, short-term durability feels fine, long-term is more of a question mark but not a red flag. For the price, I don’t expect it to last 15–20 years like some old Philips models, but if it gives a few solid years of use with a head change or two, that’s already decent value. Just don’t expect it to survive being constantly dropped on tile floors.

Out of the box, the SweetLF SWS7105 is fairly straightforward. You get the shaver itself, a USB charger with a UK plug, a small cleaning brush, the protective cap for the shaving head, and the usual paperwork. No fancy travel case or stand. For the price, I wasn’t shocked. The whole thing weighs about 340 g with packaging, and the razor itself feels light but not hollow in the hand. It’s clearly not built like a premium Braun, but it doesn’t feel like it’s going to fall apart on day three either.

The LED display on the handle shows the battery percentage, which is more useful than the vague three-bar indicators you get on some older models. It’s simple: you turn it on, and you see exactly how much juice is left. During my test, I charged it to 100% once, then just used it until it dropped below 20%. I never felt like I was guessing or worried it would die halfway through a shave. For travel, this is a big plus because you can quickly check if you need to top it up before a trip.

The head is a standard three-rotary design, nothing fancy-looking, but it’s easy enough to pop open for cleaning. There’s a small compartment where the cut hairs collect, which actually works well. After several shaves, when I opened it up, most of the mess was inside that chamber rather than all over the sink. You just tap it out, brush it, or rinse under water. Compared to older Philips or random cheap shavers I’ve had, this part is surprisingly practical.

Overall, the presentation is basic but functional: no premium feel, but the essentials are there and they’re thought through. If you like lots of accessories and a posh unboxing, you’ll be underwhelmed. If you care more about whether it shaves and charges properly, what’s in the box is enough to get going without extra purchases.

In terms of raw shaving effectiveness, I’d put this SweetLF in the “good enough for most people” category. On a normal daily routine with one-day stubble, it clears the face without much drama. I usually needed two to three passes over the cheeks and a few extra circular passes on the neck and jawline to catch the stray hairs. It doesn’t give that ultra-close blade feel, but looking in the mirror, it passed the visual test. My skin felt smooth enough for work or going out, just not that ultra-slick finish you get right after a fresh wet shave.

On longer growth (two to three days), you feel the limitations a bit more. It still cuts, but you’ll need patience. I had to slow down and go over some spots quite a few times, especially under the jaw and around the Adam’s apple. It didn’t hurt, but it took time. If you’re the type who only shaves a couple of times a week and lets the beard really grow, you might want to trim down with a beard trimmer first, then use this to clean up. For daily or every-other-day shaving, it’s much more in its comfort zone and performs better.

The pop-up trimmer is decent for straight lines like sideburns and tidying the neckline. It’s not as sharp or precise as a dedicated trimmer, but it’s fine for basic maintenance. I wouldn’t use it to shape a detailed beard, but for quick touch-ups it’s handy. Just be careful when flipping it open and shut; the mechanism feels like it could break if you’re rough with it, and one Amazon reviewer did mention snapping it.

Overall, as a daily face shaver, it does the job well enough that I didn’t feel the need to reach for my Braun every single time. For head shaving, it was surprisingly decent too, though I still prefer a blade for special occasions. If you’re expecting high-end performance from a low-cost shaver, you’ll be underwhelmed. If you want something that reliably makes you presentable with minimal hassle, it’s solid.
