Blades should be replaced about once every three years or when dulled with the Panasonic WER9606P Replacement Trimmer Blade.

Review: Outstanding and I think worth the money - But $100 for beard trimmer is a lot, so the value here is debatable. I went with the more expensive SB version. But it nails my requirements, with being water resistant, adjustable, good quality, and with a plastic guard that isn't so long, it makes it tough to trim around your nose. Some of the other trimmers out there are probably a better value? But I've tried a few and this is my favorite. Only downsides, is that it's a little larger than some of the competitors out there, and a little noisier. But it seems to cut better.
Review: A Trim Above the Rest - Impresses with Performance but Comes with a Price - As someone who values both function and finesse in grooming tools, I recently tried this Trimmer, and I was pleasantly surprised by its performance. Here's my take on this high-quality product! First and foremost, the trimmer's precision dial is a game changer, allowing for effortless length adjustments. Whether I'm aiming for a clean stubble or a fuller beard, the range of settings helps me achieve the exact look I desire without any hassle. The blades are sharp and effective, delivering smooth and even cuts that leave me looking sharp and polished. One of the standout features is its easy cleaning mechanism. The trimmer can be rinsed under water, and the detachable head simplifies maintenance significantly. This is a crucial element for me since I want to keep my grooming tools in top shape without spending too much time on upkeep. However, this impressive performance does come at a premium. While I acknowledge that quality often comes with a higher price tag, I can't help but notice that this trimmer is on the pricier side compared to others in the market. For budget-conscious consumers, that may be a point of contention. Overall, I would rate the Panasonic Cordless Men's Beard Trimmer with Precision Dial a solid 5 stars. It ticks most boxes in terms of ease of use, functionality, and maintenance. If you’re willing to invest in your grooming routine, this trimmer will not disappoint. Just be prepared to pay a bit extra for its high-quality performance!

## Questions & Answers

**Q: Does this require oil?**
A: Thank you for asking. Yes, you need to apply the oil to the trimmer before and after each use for lubrication.  Part number for it is WER203X7910. You can find it here: panasonic.encompass.com/item/10387510/Panasonic/WER203X7910/

**Q: When i go to the barbor, i ask for a 3.5. does that mean 3.5mm? or is 3.5 different with this trimmer compared to a barber 3.5?**
A: Yeah heart like an ostrich has more of the brain of an ostrich. He some how says that 1 inch is 25.4mm But, then contends that 3 inches is somehow equal to 10mm. Besides that. This product is a scam. You can buy a much cheaper version by the same company that has the same total length of dial settings, 1mm to 10mm, in a 19 setting dial.
This one technically has more options, but more settings isn't always better. Seriously who's looking at anyone's beard that closely. The addition of the blade guards is just a real kick in the teeth. If you like to keep your beard longer like I do. You can buy a very nice trimmer that will come with blade guards of various sizes that'll do just as good of a job as this overpriced piece of junk for 1/3 of this price. My advice is don't waste your money here, this is an over engineered, way to expensive product that won't do you any better than it's counterparts.
Don't waste your money on things that, claim to have more features, when their proformance is going to be the same. 
I also just have to point out that, Heart like an ostrich also gave specs about Wahl products when this product is clearly Panasonic, further confirming their lunacy.

**Q: As this is a washable unit, does it need a protective oil or some other maintenance to prevent rusting?**
A: Why does this need blade oil and other brands do not?

**Q: Cual es el corte mínimo que realiza?**
A: De 3 días

### ⭐⭐⭐⭐ Great trimmer. Not so great charger design.
*by E***C on February 9, 2025*

First things first. The trimmer is awesome. It’s smooth and comfortable. Incredibly easy to use and simple to maintain. It has acceptable battery life. It really is an awesome product for the price. I’ve always been a big fan of other Panasonic electronics and they delivered again here. The trimmer’s functionality is outstanding. Unfortunately, the package is held back by one (YMMV) flaw. The charger. It’s a heavyish base station design but with no cord. It just plugs directly into the wall and the trimmer sits vertically above it when plugged in. It’s awkward to say the least. I have to charge it in my bedroom because that’s literally the only outlet in my house capable of the task. Despite the charger I really do like the trimmer. The value and functionality more than make up for the wonky charger. I would recommend this trimmer for sure provided you have a capable outlet to charge it.
