Shame about the charging cable which is for US plugs!
This is really nice beard trimmer, feels very solid, with fine control over length of trim. Only reason I didn’t give 5 stars was that the charging plug that comes with is US which is a pain if you don’t have a US to UK adapter handy!

Used item sold as new!
It took two weeks for the item to arrive and when it did the box was not sealed. Suspicious, I inspected the item and found it had been used, with someone else’s hairs within the head of the razor. Absolutely disgusting.

Disappointing Condition
The shaver itself might be a good product, but unfortunately, it arrived in very poor condition. There were hairs stuck in the blades and even around the trimming wheel that adjusts the height. The lower black plastic part was completely scratched up, making it look used or poorly handled. It’s really disappointing to receive something in this state, especially when buying a new item.

Take care - it does not have. U.K. power supply.
Bought from and for use in UK. Arrived with a US power supply. Luckily my old Phillips razor also has a 15v / 45W power supply !! Very poor.

Best beard trimmer on the market. Charge last a very long time. Feels like I only charge it every couple to few months and I use it every day. Really well made. Runs smooth and no signs of slowing down, well after a year of almost daily use. Lots of options for length (.2 through 3 blade, even without guards). Great sophisticated and sleek look. Cuts well, I shave my beard, outer ear, eye brows and body hair. One of the best and most reliable products I own in any category

My trusty Wahl of the last 10+ years finally bit the dust. I had traditionally used cheaper Wahls or other trimmers you'd find on clearance at Winners, TJ Maxx, etc. As a bald man my beard is my hair of choice and I have been trimming my beard for 20+ years at this point. I did a bunch of research and this one was highly lauded as being the most precise trimmer. I gotta say this thing met all of my lofty expectations and surpassed them. The 0.2mm adjustment will be excellent for doing a taper/fade from bald to full beard. I still have to get used to the precision this device offers and have only used it once so far. But my god that first experience was earth shattering and showed me why it's worth the price of admission. Super high quality feel, easy to maneuver, and as advertised extremely precise. A single pass gets the hairs to the same consistent length like I've never experienced. Usually I would have to do a few passes, and then go guardless to get any stray long hairs sticking out. This trimmer passes the "hand test" where I rub my hand on the side of my face/beard and can feel every follicle touching my hand at the same length. It's truly wild how powerful, and premium this device is. After getting this device it's hard to believe that I hadn't upgraded sooner, especially with how often I trim my beard and maintain it. For any of you guys out there questioning if this is worth the investment over our traditional cheaper trimmers, I cannot speak high enough praise about this product. And makes me question and regret taking this long to get a device of this quality. The precision dial is easy to use, and doesn't slip like traditional adjustable plastic guards. Do yourself a favour, and step up your trimmer game and treat yourself to this device. If you shave/trim your beard regularly you'll immediately be able to tell the quality and precision of this device is second to none. I'm still shocked I spent this much on a trimmer, but have absolutely zero regrets and look forward to mastering it over the coming months/years and enjoying it for the forseeable future!

It doesn't get better than this, let's just try to leave it at that. But seriously, there's no messing around with guards, no attaching anything, no weird gadgets, it just... maintains my stubble at a perfect three-day length. The battery lasts ages, charges quickly, and you can use the shaver while it's charging. It comes in a nice sleeve, of sorts, as pictured. And to address another reviewer - of course this only comes with a US charger, it is being sent from the US. Just check where it is being sent from before giving it 1/5 stars. It's more or less impossible to miss that detail, given that the postage is usually weeks away, and given that it explicitly says on the product's page, i.e. here, that it is coming from the US and it says that again throughout the tracking (of course). I've been using it for a long time with an adapter, with zero issues at all. To get it locally in Australia, that will set you back over $300 usually, so I think... to get this for $150 or however much, it's insanely good value, and it is so easy to either use an adapter (US to Australia of course) or to just buy a new cable, if you really don't want to use an adapter. It's not a big deal, and as I said, it saves you so much money. Shipping from the US was fast, great service from Amazon, as usual 🙂 Truly, I can't recommend this highly enough. I spent so much money over the years, going from one trimmer to the next. I've had my current version of this shaver since 2022, but have recently re-ordered one, so that I have a spare. That's how much I love it! It just makes shaving a much nicer experience, and I've had plenty of comments saying that my stubble "always looks nice, neat, and at the right length". Winning!
