## Description

Including: Full steel blades and head, sleek and durable steel design; 100% waterproof; 120 minutes of Lithium Ion run time, 30 quick adjustable lengths zoom wheel in 0.2mm increments (0.4mm to 10mm range) and 1 sturdy reinforced guard attachment to get your precise, even, desired length. This trimmer also cuts hair. *The grease found as you remove the trimmer head is there to ensure consistent trimming performance over time, so you’ll have a trim that’s as smooth as day one.

Review: I've only had it a day, but I love it already. - I have only had this for a day but I already love it. I have a similar Philis Multigroomer trimmer (7790/40 model), which comes with about 30,000 different blade guides and other accessories. I really like the multigroomer but I almost never use the kazilion blade guides, etc. When I was cutting my own hair (thank you, pandemic), I graduated to serious clippers (Andis, Babyliss) because the multigroomer wasn't quite up to the task. I did use it occasionally as a beard and mustache trimmer, but the multitude of guards and having to swap them around all the time made it rather tedious. I've had half a dozen other trimmers of various brands, too, and have never been in love with any of them. There's the backstory. On to the good part. Enter the Philips OneBlade 360. "But wait, that's not this trimmer!" you exclaim. I stumbled on that trimmer a couple of days ago and, well, why not? Figured I would give it a try. Really like it! But that's a whole different review. It does not, however, come with a case, the search for which led me to THIS trimmer. When I saw the 9810, I quickly realized it is basically the same trimmer as the multigroomer, without all the blade guides, etc., and the really slick dial-in trimming adjustment. Sold. So why did I buy it when I had just bought the OneBlade 360? They are really good at different things. The OneBlade 360 I bought, which is the face and body trimmer version, is great for edging, shaping, clean up, manscaping, etc., and a quick face clean up when I don't want to wet shave. It's super maneuverable, quick, and versatile. In short, I like it for quick cleanups and edging but not so much for an all-out trim. The BT9810 is excellent for more serious trimming. I get the benefits of a trimmer with multiple blade guards without all the fiddling around. It is bulkier and less nimble than the OneBlade for clean-up and shaping but does a better job at the more involved or thicker cutting. You aren't going to use this in other places either, like for manscaping. I got more consistent length when setting this to a 5mm cut and hitting my mustache and beard than with the OneBlade. The OneBlade gave me nicer edges. Probably because it is just more maneuverable and shaves more like a razor in some ways. So, I wound up with two clippers I didn't know I needed. I love them both. And if you are a fan of Philips multigroomers but don't need or want 30,000,000 separate guides, this is for you. Have someone on your holiday list that you want to spoil? Buy them this trimmer. Or buy them both. Or buy them for yourself. All the other lackluster trimmers are going to the thrift shop now. I'll keep the multigroomer for those oddball occasions when I want the versatility of multiple blade guards, the body groomer, and interchangeable blades. If you read this far, you definitely deserve to buy yourself this trimmer.
Review: Smooth beard trimmer, good battery life - Only used it a few times so far but so far: Does a smooth shave with and without the guard attachment; very smooth! works well; battery life seems great, I charged it for like 15 minutes and could use it right away; it feels good and solid and sturdy; easy to open and clean; it's nice that it is waterproof. The small case is nice for travel. I do not think it would be good for edging at 0.4MM shortest length, I mean it is enough to set a target line or something but you really need a razor or a shaver that goes fully down to the skin. But it is a beard trimmer, not shaver, so that is OK, I shave with something else anyways. Overall very happy with the purchase. Would be nice for $100 if it came with a couple other guards just in case yours broke though or if you wanted more length. If durability is an issue I will report back but so far it is great.

### ⭐⭐⭐⭐ Excellent beard trimmer
*by A***R on July 14, 2025*

This is a great beard trimmer, solid and well built. The thing I really like is the fact it doesn't need any additional combs/guards up to 1cm, it's all built into the sturdy metal head. There is a dial on the trimmer that enables you to set the trimming length required, this is a god send for me as I travel a lot and am forever losing the guards for my OneBlade. Downside 1 - it's a sturdy unit with a lot of metal so is therefore a lot heavier than something like the OneBlade. It's also quite big but even given it's size it works very well and allows pretty efficient smooth trimming. It's best gripped by the rubberised part at the top of the unit for the best results. Downside 2 - it uses a special proprietary connector which is not USB. It comes with a 120V charger so not much use when travelling outside of countries that don't have 120V. You can get a USB C to special connector adapter from Yinke which seems to work well so far but means another thing to lose when travelling. Downside 3 - to do precision lines and edges you'll still need something like a OneBlade. I've given this a 4/5 rather than a 5 due to the downsides but overall a great product all the same.
