AI Verdict
This 3-key, 1-knob, 1-screen Hall Effect keypad with 8000Hz polling is for rhythm gamers needing precise 0-4.000mm rapid trigger actuation.
This keypad is a strong contender if your primary goal is to shave milliseconds off your rhythm game inputs with rapid trigger and magnetic switches. Its 8000Hz polling rate and customizable actuation points are specifically designed for that niche, but its limited keys and low-res screen mean it's not for general use. It's a tool for a very specific job.
If you need a more versatile keypad for general use or other gaming genres, look for options with more keys and a more robust software ecosystem.

Pros
- Features 3 Hall magnetic linear switches for precise input without physical contact wear.
- Offers 0-4.000mm custom trigger and release points for fine-tuned actuation in rhythm games.
- Includes a 0.96-inch IPS color screen (160x80 resolution) for visible key range and button counting.
- Supports hot-swappable Hall magnetic switches, allowing for switch replacement.
- The keys and knob are fully programmable for custom keybinds or macro combinations (e.g., Ctrl/Alt/Shift + any keys).
- Boasts a high-speed 8000Hz polling rate via USB-C connectivity.
Cons
- The 0.96-inch IPS screen has a low 160x80 resolution, comparable to a 1998 Tamagotchi display.
- Initial setup and software configuration for rapid trigger settings can be confusing for new users.
- The 8000Hz polling rate is largely unnecessary, as most monitors refresh at 240Hz or below, making the extra reports negligible.
- Brand legitimacy and long-term software support are questionable, with no clear website or warranty page.
- Requires calibration before first use or after firmware updates, adding an extra step to setup.
Dimension Scores
While the Gateron Jade Pro Green switches are magnetic linear, the keypad's 3-key layout and rapid trigger focus make it unsuitable for general typing tasks.
It uses a wired USB-C connection with an 8000Hz polling rate, which typically indicates a stable and low-latency connection for gaming.
The product specifications and user reviews do not mention any backlighting for the keys, only a small IPS screen.
The material is plastic, and while users report it working well, there are no specific details to suggest exceptional durability or premium construction for its price point.
Best For
- OSU! players seeking a competitive edge with rapid trigger functionality.
- Geometry Dash enthusiasts who need extremely fast and consistent key presses.
- Rhythm game players who want a dedicated macro keypad with customizable actuation.
- Users looking for a budget-friendly rapid trigger keypad alternative to higher-priced options.
Not Recommended For
- General typing or productivity tasks, as its features are specialized for rhythm gaming.
- Users expecting extensive software support or a polished user experience from a major brand.
- Anyone who finds complex software setup and calibration frustrating.
Watch Out For
- The 8000Hz polling rate is mostly marketing fluff; your 240Hz monitor won't show the difference, making it digital shouting into a voicemail box.
- Setting up the rapid trigger can be a headache; one user mentioned needing assistance and guidance from a Discord server due to confusing instructions.
- The brand 'BTXETUEL' (as seen on some listings) lacks a clear website or warranty, so don't expect future software updates or support if Windows changes.
- You might need to calibrate it before first use or after firmware updates, which is an extra step not typical for most peripherals.
- The screen's 160x80 resolution is pretty low, so don't expect crisp custom animations; it's more for basic info like key counts.

What Buyers Say
The most surprising thing about this keypad is how many rhythm gamers swear by its rapid trigger despite its budget price and questionable brand support. Users consistently report a noticeable improvement in game performance due to the customizable actuation points. However, getting it set up can be a real pain, with confusing software and a need to join a Discord for help. The tiny 160x80 screen is more of a novelty than a functional display, and the 8000Hz polling rate is largely marketing fluff that won't impact most players.
“Dude, this thing actually made my OSU scores better, but setting up the rapid trigger was a nightmare, I almost threw it at the wall trying to figure out the software.”
Common Praise
- Rapid trigger functionality significantly improves performance in OSU! and Geometry Dash.
- Customizable actuation points (0-4.000mm) allow for fine-tuning to individual playstyles.
- Hot-swappable magnetic switches offer flexibility for switch replacement.
- The keypad is seen as a cost-effective alternative to more expensive rapid trigger options like Wooting.
- The knob can be bound to in-game volume or other custom functions.
Common Complaints
- Software setup for rapid trigger settings is confusing and difficult for first-time users.
- The 0.96-inch IPS screen has a very low 160x80 resolution, making custom animations look pixelated.
- Concerns about the brand's lack of official website, warranty, or long-term software support.
- Calibration is sometimes required, which is an extra step in the user experience.
- The 8000Hz polling rate is considered excessive and provides no real-world benefit for most setups.
Ownership Tips
- You'll probably spend a good chunk of time in a Discord server trying to get the rapid trigger settings just right, because the included instructions are not enough.
- The little screen is fun for like five minutes, then you realize you never actually look at it while playing.
- Don't expect any fancy RGB lighting on the keys themselves, it's just the screen that lights up.
- The magnetic switches feel different than mechanical ones, and it takes a bit to get used to the lack of a physical contact point.
- You'll need to keep the calibration steps handy, because it might ask for it after updates or if you mess with settings.
Frequently Asked Questions
What are Hall magnetic linear switches?
These switches use magnets instead of physical contacts, which means they won't wear out in the traditional sense and allow for adjustable actuation points.
What does 'Rapid Trigger' mean?
Rapid Trigger allows a key to register input the moment your finger moves upward, not just when it's pressed down, potentially shaving 5-10ms off a bottom-out press for faster repeated inputs.
Can I customize the keys and knob?
Yes, both the keys and the knob can be programmed with any single key or combinations like Ctrl/Alt/Shift + any key.
Is the 8000Hz polling rate actually useful?
For most users, especially with monitors refreshing at 240Hz or less, the 8000Hz polling rate provides no noticeable benefit over 1000Hz; it's largely overkill.
Do I need to calibrate this keypad?
Yes, the manufacturer states that calibration is sometimes required before first use or after a firmware upgrade.
Buying Guide
When you're looking at a specialized keypad like this, you're buying it for one thing: speed and precision in rhythm games. Don't get distracted by features like screen resolution or an ultra-high polling rate if your monitor can't keep up. Focus on the rapid trigger and how customizable the actuation points are, because that's where the real performance gain is for games like OSU! and Geometry Dash.
Rapid Trigger
This is the secret sauce for rhythm games. Instead of a fixed point, the key registers both on press and release, letting you spam notes faster and with less effort, like a super-responsive car accelerator and brake pedal.
Hall Magnetic Linear Switches
These switches use magnets, so there's no physical contact to wear out over time. Think of it like a touch-sensitive button that lasts forever, giving you consistent performance without degradation.
8000Hz Polling Rate
This is how often the keypad tells your computer it's been pressed. While a higher number sounds better, it's like sending 8000 messages a second to someone who only checks their phone 240 times a second – most of those messages just get ignored by your monitor.
Custom Trigger/Release (0-4.000mm)
This lets you set exactly how far you need to press a key for it to activate, and how far you need to lift it for it to reset. It's like adjusting the sensitivity of your gaming mouse down to the millimeter, giving you ultimate control.
Alternatives
If this keypad doesn't fit, look for other rapid trigger keypads with more keys for broader macro use, or consider full-sized keyboards with similar magnetic switch technology if you need it for general gaming and typing.
