    • Perfect except one thing
Size: BT9810/40 + 2 Accessories Color: Black
Really great trimmer. It makes me want to trim my beard because of how easy and powerful it is. It feels great in the hand and the metal clipper gives a very even trim. So much better than plastic guards which I always feel never cuts perfectly even. There is only one downside. The lowerest it can cut is 0.4mm. So if you want to do some shaping, it doesn’t get rid of all of the hair unfortunately. But if you have a razor, can use the in addition to the trimmer for shaping. I like to shape my mustash ends so it doesn’t look like a handlebar. With my old trimmer, I could do this easily by removing the guard. But with this trimmer, you can’t remove the guard, so it’s a bit inconvenient. But have a razor on hand and it can solve it. Still I would like if it could go down to 0. Bit of a bummer but overall, it’s still the best trimmer I’ve ever used. So I’m happy with it ... show more

    • The best consumer electronics device I've ever owned
Size: BT9810/40 + 2 Accessories Color: Black
The Philips Norelco 9000 is perhaps the best consumer electronics device I've ever owned. I bought this in 2022 to replace the trusty Philips Norelco BeardTrimmer 7300 that I had purchased way back in 2012. Now, three years later, I am moved to write this review to extol the virtues of this wonder. The battery life is astonishing. I use it regularly to trim my full beard and other facial hair, and I honestly think I've only ever had to recharge the battery a handful of times, maybe once a year? It has never nicked my skin. Although the trimming head is wide enough for heavy duty chores, it is surprisingly precise. It is very handy and travels extremely well. The adjustment for trimming hair length is stays set in place unless you decide to easily change it. Maybe in 2032 I'll be ready for my next Philips Norelco trimmer, but until then I am delighted that I have this. ... show more

    • Excellent beard trimmer
Size: BT9810/40 + 2 Accessories Color: Black
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. ... show more

Lets preface this purchase with 10 years of usage with a diffrent brand, my old one was 4+ years old, I used in the shower from top to bottom,but the battery was failing.So i choose this one due to the waterproof and battery ion upgade, I hated it the first time i used it, but the more i used it the better it gets.

    • Smooth beard trimmer, good battery life
Size: BT9810/40 + 2 Accessories Color: Black
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. ... show more

    • Buy it, it is worth the money. No con's at all.
Size: BT9810/40 + 2 Accessories Color: Black
This is the perfect beard trimmer. I have owned them all, and this is sharp, easy to use, easy to clean and accurate. I have always had blade attachments but this wheel allows me to adjust my trim perfectly. I was concerned about the amount the adjustment would allow, don't be. Plenty long enough, in fact, I stored the plastic comb, don't need it. ... show more
