AI Verdict
This 5.1-ounce, 3-key USB-C macro keypad with Hall magnetic switches and an 8000Hz polling rate is for rhythm gamers needing rapid trigger response.
This macro keypad is a strong fit for a very specific niche: rhythm game players who can leverage the rapid trigger Hall effect switches and 8000Hz polling rate for competitive play. Its compact size and customizable keys cater directly to this use case, but its limited functionality and plastic build make it unsuitable for broader applications.
If you need more than three keys or a more robust build, look for larger macro pads with metal chassis and more extensive software support.

Pros
- Features 3 Hall magnetic linear switches with 0-4.000mm custom trigger release, allowing for rapid trigger functionality.
- Offers an 8000Hz polling rate via USB 2.0 high-speed connectivity for minimal input delay.
- Includes a 0.96-inch IPS color screen with 160x80 resolution for visible key range and button counting.
- Keys and the single knob are fully customizable for various functions or macro assignments.
- Supports hot-swappable Hall magnetic switches, allowing for easy replacement and calibration.
Cons
- The 8000Hz polling rate is largely theoretical for most setups, as typical monitors refresh at 240Hz or below.
- The 0.96-inch IPS screen, with its 160x80 resolution, is described as having the fidelity of a 1998 Tamagotchi.
- Setup can be confusing and difficult for first-time users, often requiring external assistance.
- Requires calibration before initial use or after firmware updates, which adds a step to setup.
- Constructed entirely from plastic, which may not feel premium for some users.
Dimension Scores
With only three keys, this device is not designed for typing, and its magnetic switches are optimized for rapid actuation rather than traditional typing feel.
It uses a wired USB-C connection with an 8000Hz polling rate, which typically ensures a stable and responsive connection.
The product specifications and feature highlights do not mention any backlighting for the keys.
The device is made of plastic and weighs only 5.1 ounces, indicating a lightweight but not particularly robust construction.
Best For
- Rhythm game players focused on OSU! or Geometry Dash seeking a competitive edge.
- Users who need precise, customizable macro inputs for specific PC applications.
- Enthusiasts looking to experiment with rapid trigger technology at a low entry point.
Not Recommended For
- Anyone needing a full-sized keyboard for typing or general productivity.
- Users expecting a plug-and-play experience without needing to calibrate or troubleshoot.
- Individuals prioritizing premium build materials or extensive RGB lighting.
Watch Out For
- The 8000Hz polling rate is largely marketing, as most displays can't keep up, creating a bottleneck.
- The 160x80 resolution screen is tiny and offers limited practical utility beyond basic feedback.
- Initial setup and firmware updates necessitate calibration, which can be a hurdle for new users.
- The plastic construction means it won't feel as substantial as metal-cased alternatives.

What Buyers Say
This little macro pad is a niche tool, really built for rhythm game players who are chasing every millisecond. Reviewers point out the 8000Hz polling rate, while technically high, is often overkill because most monitors can't even display that many updates. The tiny 0.96-inch screen, with its 160x80 resolution, is more of a novelty than a functional display, often compared to old Tamagotchis. Setting it up can be a headache, with users frequently needing to hit up Discord for help and firmware.
“Look, if you're trying to shave off 5ms in OSU, this thing is probably it. But don't expect a fancy screen or easy setup, it's a pain to get going.”
Common Praise
- The rapid trigger feature genuinely shaves off milliseconds, which is crucial for top-tier rhythm game scores.
- The Hall magnetic switches are hot-swappable, allowing for easy replacement and customization.
- The keys and knob are highly customizable, letting users assign specific macros or key combinations.
- The 0-4.000mm custom trigger release offers fine-tuned control over actuation points.
Common Complaints
- The 8000Hz polling rate is often seen as excessive and not fully utilized by typical gaming setups.
- The 160x80 resolution screen is considered low-fidelity and not very useful during gameplay.
- Initial setup and calibration processes are confusing and require external guidance.
- The plastic construction feels less premium compared to other gaming peripherals.
Ownership Tips
- You'll probably spend some time in Discord forums figuring out the software and calibration.
- The rapid trigger setting takes some getting used to; it's a different feel than standard mechanical switches.
- The tiny screen is mostly for show, you won't be looking at it mid-game.
- Calibration is a recurring task, especially after firmware updates, so keep the instructions handy.

Buying Guide
When you're looking at a macro keypad like this, you're really buying a specialized tool. Don't think of it as a mini-keyboard. You need to understand that features like 'rapid trigger' and '8000Hz polling rate' are for very specific, high-speed input scenarios, mostly rhythm games. If you're not playing those, you're paying for features you won't use. Focus on how many keys you actually need and how easy the software is to use for your specific macros.
Hall Magnetic Linear Switches
Unlike traditional mechanical switches that use physical contacts, these use magnets. This means they can detect actuation based on distance, allowing for features like 'rapid trigger' and adjustable actuation points (0-4.000mm). It's like a gas pedal that can be sensitive to the slightest touch or a deeper press, depending on your setting.
Rapid Trigger
This is the secret sauce for rhythm gamers. It means a key registers not just when you press it down, but also the instant you start to release it. Imagine a light switch that turns off the moment you lift your finger, not just when it clicks back up. This can give you a tiny speed advantage in games where every millisecond counts.
8000Hz Polling Rate
This refers to how often the keyboard tells your computer it's being pressed – 8000 times per second. In theory, this means almost no delay. However, your computer and monitor also have refresh rates. If your monitor only refreshes 240 times a second, it's like sending 8000 messages to someone who only checks their inbox 240 times; most of those messages get ignored. It's often overkill for most users.
Alternatives
If this keypad doesn't fit, look for macro pads with more keys (e.g., 6-key or 9-key layouts) if you need more functions, or consider models with dedicated software for easier macro programming if you're not into rhythm games.
