Review: Not bad at all , 5 yrs of use. - Love the razor, for all it's functionality and ease of use, I have had mine since 2021, but as others have noted, the plastics failed. In my case the skin guard failed as in being able to keep it on the body of the razor it self. Everything else still works perfectly, so much so i ordered another one and will keep the original with out the skin guard for close up shaving..
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.

## 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

### ⭐⭐⭐⭐⭐ Not bad at all , 5 yrs of use.
*by D***. on February 27, 2026*

### ⭐⭐⭐⭐⭐ Outstanding and I think worth the money

### ⭐⭐⭐⭐ Reasonable quality, but somewhat flimsy
*by P***Y on March 6, 2026*

Works reasonable well, feels cheap, but I suppose that's the price point. It has an old school clicky power switch which requires you to press it past the detent in order for it to remain in operation. Perhaps that's a "feature"? I use this for specific tasks, and have two others. One pair for body grooming and third for facial. All three are different makes and models. So, this is a good addition to the task it will be used for.
