V0 Ultra 8K Polling Rate Wireless (2.4 GHz & Bluetooth) ZMK Custom Number Pad with Hot-swappable Banana Switches 360-Hr Battery OSA PBT Keycaps RGB Backllit for Mac Windows Linux

Bought this to go with my new V1 ultra after having used a Epomaker model for a couple of years. This thing is superb so far. Sounds nice, easy to program macros in web based app. A great companion.

Like many accessory keyboards, this being a ten key, there are loads of options available here on Amazon with drastically varying price point. Unfortunately, this is a drastically overpriced ten key for what it is. Positives: -The macro keys are a nice plus for a ten key. -Volume knob works well and button click is nice. -The pad stays put during use, even on my smooth desktop. -Wireless. -Overall usage is perfectly fine. -I do like the shape of the keycaps. Considerations: -Web based configuration... whilst nice, may also go offline in a year. I don't understand why, if this keyboard can be controlled via a website, a stupidly simple app can't be used locally that does the same without requiring any permissions. Sure, you could clone the website, but that's not the point, you should NEED to. Negatives: -As mentioned previously, this is far too expensive. I have 100% aluminum based, full-sized keyboards with doubleshot keys, macro keys, volume controls, better switches, and more, for the same price point. -100% plastic build makes the $70 (when reviewed) price very questionable. Overall: -Whilst I found no actual issues with this Keychron ten key, it's far too expensive, even for a niche product, to recommend against other products on Amazon. If you can pick it up for $30 or less, go for it then. This review is for "Keychron V0 Ultra 8K Polling Rate Wireless (2.4 GHz & Bluetooth) ZMK Custom Number Pad with Hot-swappable Banana Switches 360-Hr Battery PBT Keycaps for Mac Windows Linux"

I picked this up expecting a simple wireless numpad, but it feels much more like a compact productivity controller. The build quality is excellent, the keys feel solid and responsive, and the included rotary knob is surprisingly useful for volume control and quick adjustments while editing or multitasking. I also appreciate that it works across Mac, Windows, and Linux without any hassle. What really impressed me is how customizable it is. The programmable side buttons and hot swappable switches make it easy to tailor for video editing, spreadsheets, streaming controls, or even creative applications like CAD and 3D printing workflows. The overall design looks clean and modern without the overly flashy gamer aesthetic. Battery life also seems very good so far. If you want a compact premium desk accessory that is both functional and visually polished, this is a great option.

This is a premium product that can be found from other vendors for half the price. Let me start with that. Let me also state there is no excuse for this to cost as much as an aluminum keyboard with QMK/VIA support and better switches, when it is plastic and only an accessory keyboard. Keychron has a habit of out-pricing their own potential customers and then blending lack of sales for a product being good. This is a good product, but it is crap at $70. Should be $35-$50. Functionally, though, it is perfectly fine. Feels good to use, looks good, but manipulating it is average, at best. Should have 15-20% more weight.

As a long‑time Keychron fan, the V0 Ultra 8K shows exactly why this company is the GOAT of mechanical keyboards. It delivers near‑instant responsiveness thanks to its 8,000 Hz polling rate, which is eight times faster than standard keyboards and effectively eliminates input lag. That speed matters whether I'm entering numbers in a spreadsheet or tapping out quick macros in a game. Powering all of that is a 1,800 mAh battery that lasts up to about 360 hours though I'll be honest, Ive not depleted that battery yet so really cont speak to how long it will truly last between charges. In terms of connectivity, it connects seamlessly with low‑latency 2.4 GHz wireless, Bluetooth, or USB‑C. Once paired, switching between devices is effortless. Customization is where this numpad really shines. The keys are hot‑swappable, and Keychron's Launcher software lets me remap every key, assign macros, and even fine‑tune RGB lighting. There's also a programmable rotary knob and extra macro keys that make repetitive tasks faster and give me more creative control. The build quality feels premium: a robust CNC‑machined aluminum chassis, gasket mount, and layers of sound‑dampening foam give it a solid, muted feel, and the double‑shot PBT keycaps will outlast anything ABS. Everything I touch on this pad feels sturdy. If I had one minor wish, it would be for a little more weight. The aluminum body is solid, but a bit of extra heft would make it feel even more planted on my desk. Even so, this numpad remains my favorite in its class, combining great performance, thoughtful features, and Keychron's trademark quality. Pros 8K polling rate delivers instant input hot‑swappable switches and macro keys plus a programmable knob for deep customization triple‑mode connectivity Cons it could use a bit more weight to feel more anchored Hot Take Keychron packed a full‑sized keyboard's worth of innovation into a numpad; the only thing light about it is the weight.

Really makes you wonder why the price is so high. It's definitely a nice numpad, but what sets it apart from any other one that costs half as much? The 8k polling rate to me in a device like this is a gimmick. It's not like you're using this numpad to game with. 8k polling rate goes a long way in a gaming keyboard or gaming mouse because it gives you very low latency, but for a numpad even Bluetooth is good enough, and I think the 8k polling rate is what's driving the price.

I ordered the V0 Ultra 8K number pad to act as the perfect companion for my 75% keyboard, and it has completely changed the ergonomics of my workstation. One of the most wonderful things about a dedicated pad like this is the freedom to place it on the left side of the keyboard for a "southpaw" layout or even to the far right of the mouse for macro shortcuts. Moving the numpad to the left has been a huge win for my productivity because it allows me to input data with my left hand while keeping my right hand on the mouse, which feels much more natural and efficient during long day trading sessions. The build quality is excellent, and the 8000Hz polling rate makes it feel just as responsive as my primary board with zero noticeable lag. Just like a few of my other Keychron keyboards, I went with the Banana switches on this unit. The tactile feedback is exactly what I was looking for. These switches have that early-stage bump that makes numerical entry feel very deliberate and snappy, which is a major upgrade over the mushy feel of standard office numpads. For anyone running Linux like I am, you will definitely need to add the specific udev rule to your system so the Keychron Launcher web tool can communicate with the ZMK firmware over USB. I have included a screenshot of the Launcher page to show how deep the customization goes. Being able to remap every single key and macro through the browser is incredibly convenient. The PBT keycaps feel very premium, and the battery life has been stellar. This unit can last several weeks of work without needing a charge.

Keychron does it again. A numpad is essential for me and this nails it on a lot of levels. First, even though this is a plastic body, it feels appropriately weighty with a solid high quality case. It's put together quite nicely. It follows the design elements of most of Keychrons other products with a USB port on the back, next to the toggle for wireless/BT. The knob is metal, which surprised me. It feels really good to turn with zero wobble and sharp tactility. The OSA keycap profile is one of my favorites and I'm super happy to see them in use here. It's extremely comfortable to use, very natural in profile/angle. The rubber feet on the bottom ensure it isn't going anywhere as you tenkey. On the software side it uses the familiar Keychron launcher web UI, which is fantastic. Any customization will be done there. Per key RGB, macro assignments, polling rate, etc. Very easy to use anyone can do with no confusion. There is only one thing I can think to be critical of and this isn't a flagship product so I can't knock it for this really, but I'm not a fan of Keychrons in house switches. The Gateron Banana switches feel much better in my opinion. But considering this isn't a Q board I think they are acceptable and most people will probably find them very comfortable compared to what they have tried before. I've used several other numpads from other companies and the quality and feel doesn't really come close. If there is one thing Keychron is consistent in, it's the quality/feel of their keyboards and this numpad carries that on.
