- The keys and knob are fully customizable, supporting single keys or Ctrl/Alt/Shift combinations.
- Magnetic switches are reported to not wear out in the traditional sense, contributing to durability.
- Rapid trigger functionality can shave 5-10ms off a bottom-out press, benefiting rhythm game performance.
Cons
- The 0.96-inch IPS screen has a low 160x80 resolution, described as having the fidelity of a 1998 Tamagotchi.
- Initial setup can be confusing and difficult for first-time users, often requiring assistance from a Discord server.
- The 8000Hz polling rate may be largely unutilized by typical setups with monitors refreshing at 240Hz or below.
- The brand lacks an official website, warranty page, or firmware changelog, raising concerns about long-term support.
- The knob's placement can lead to accidental activation during intense gameplay.
Dimension Scores
The Gateron KS-20 White magnetic linear switches offer a smooth, consistent feel with customizable actuation from 0-4.000mm, which is highly beneficial for rapid, repetitive inputs in rhythm games.
Utilizing a wired USB-C connection with an 8000Hz polling rate provides a highly stable and low-latency connection, crucial for competitive gaming.
The product specifications and user reviews do not mention any backlighting for the keys, only a small IPS screen.
The presence of a USB-C port and a braided cable suggests a reasonable build, but the lack of brand information and the budget price point prevent a higher score.
Best For
- Competitive OSU! players needing precise, low-latency inputs for high scores.
- Geometry Dash players seeking a dedicated macro keypad with rapid trigger functionality.
- Users who need a compact, customizable 3-key macro pad for specific game actions or shortcuts.
- Enthusiasts looking to experiment with rapid trigger technology at a budget price point.
Not Recommended For
- General productivity or typing tasks, as it only has 3 keys and a knob.
- Users expecting extensive brand support, official documentation, or easy-to-access firmware updates.
- Anyone who requires a full-sized keyboard or a macro pad with more than 3 keys.
Watch Out For
- The 0.96-inch screen's 160x80 resolution is very low, making custom animations or detailed information display limited.
- Setting up the keypad's custom trigger release and other features is reported to be confusing, often requiring joining a Discord server for guidance.
- The 8000Hz polling rate, while technically high, offers little practical benefit for users with monitor refresh rates below 240Hz.
- The brand, BTXETUEL, appears to lack an official website or warranty information, which could complicate support or repairs.
- The physical knob can be accidentally 'bonked' during gameplay, potentially disrupting performance.

What Buyers Say
This little keypad is a hit with rhythm gamers, especially for OSU! and Geometry Dash, because of its rapid trigger magnetic switches that let you hit notes super fast and precisely. People really dig the 8000Hz polling rate, even if their monitor can't quite keep up. The small screen is a cool touch for showing stats or custom stuff, but don't expect a high-res display. The biggest hurdle seems to be getting it set up just right, and the brand's lack of a proper website makes finding help a bit of a scavenger hunt.
“Dude, this thing for OSU is actually kinda cracked, but setting it up was a nightmare and I keep accidentally spinning the knob when I'm trying to full combo. Still, my scores are up.”
Common Praise
- Rapid trigger feature allows for more precise and faster inputs in rhythm games.
- Magnetic switches offer durability because they don't wear out like traditional mechanical switches.
- The 0.96-inch IPS screen is useful for configuring deadzones and displaying basic information.
- Customizable keys and knob provide flexibility for game-specific macros and shortcuts.
- The 8000Hz polling rate delivers extremely low input latency.

Ownership Tips

- The small screen is more for novelty or quick checks than for detailed information, like a Tamagotchi display.
- Accidentally hitting the knob is a real thing, you might need to adjust your hand position or disable it for certain games.

Frequently Asked Questions
What kind of switches does this keypad use?
It uses 3 Hall magnetic linear switches, specifically Gateron KS-20 White Switches, which are hot-swappable and support rapid trigger functionality.
Can I customize the keys and the knob?
Yes, both the keys and the knob can be customized to any key or combination of Ctrl/Alt/Shift + any keys.
What is the screen for?
The 0.96-inch IPS color screen displays visible key range, button counting, and supports custom animations. You can also customize the first line of text, like your ID.
Is it difficult to set up the rapid trigger feature?
Users have reported that initial setup, including configuring rapid trigger, can be confusing and may require consulting the brand's Discord server for assistance.
Does the 8000Hz polling rate make a big difference?
While it offers extremely low latency, the practical benefit of 8000Hz polling might be limited if your monitor's refresh rate is 240Hz or lower, as the system can't display updates as quickly as the keypad reports them.
Is this keypad compatible with mobile devices like an S21?
The product is specified as compatible with PC, and user questions about S21 compatibility suggest it's not explicitly designed for mobile, though some users inquire about it.
Buying Guide
When you're looking at a macro keypad like this, you're really buying into specialized performance for specific games. Don't think of it as a mini-keyboard for everyday tasks. You need to care about things like how fast a key registers when you press it (actuation) and how quickly it resets when you lift your finger (rapid trigger). The high polling rate means the keypad talks to your computer super fast, but your computer and monitor also need to keep up to show you those quick inputs. It's a tool for gaining a competitive edge, not a general-purpose gadget.
Rapid Trigger (0-4.000mm Custom Trigger Release)
This lets you set exactly how far you need to press a key for it to activate, and crucially, how little you need to lift it for it to reset. Imagine a light switch that turns on and off with the tiniest flick, letting you spam inputs much faster than a regular switch that needs a full press and release.
Hall Magnetic Linear Switches
These switches use magnets instead of physical contacts, which means they don't wear out mechanically over time. They also enable the rapid trigger feature, giving you a smooth, consistent press without any scratchiness or inconsistent actuation points.
8000Hz Polling Rate
This is how many times per second the keypad tells your computer its status. A higher number means less delay between your action and the computer registering it. Think of it like a super-fast messenger; the more messages it sends per second, the quicker your computer knows what you're doing.
0.96-inch IPS Color Screen (160x80 Resolution)
This small screen can show you things like how many times you've pressed a key or your current settings. It's not for watching videos, but it's handy for quick visual feedback or personalizing your keypad with a custom image or text.
Alternatives
If this keypad doesn't fit, look for macro pads with more keys (e.g., 6 or 9 keys) if you need more programmable inputs, or consider options from brands with more established software and support if ease of setup is a priority.
