What Buyers Say
Many users are surprised by the premium typing experience, often describing the sound as 'creamy' and the feel as smooth, especially considering the sub-$100 price point. The spacebar, in particular, receives praise for its sound profile. However, the Windows-only customization software and the lack of labeled secondary functions on the keycaps are recurring frustrations, especially for macOS users. The plastic case, while making it lightweight, is a trade-off for some who prefer metal.
“Dude, for eighty bucks, this thing types like a dream, seriously, the sound is so satisfying, but why can't I remap keys on my Mac, it's kinda annoying.”

Buying Guide
When you're looking at mechanical keyboards, don't just focus on the switches. The mounting style, like gasket mount, significantly impacts how the keyboard sounds and feels when you type. A larger battery means less charging, which is a big deal for wireless use. Also, check if the software supports your operating system for full customization, not just basic plug-and-play. Hot-swappable switches are a game-changer if you ever want to try different switch types without buying a whole new keyboard.
Gasket Mount Structure
This means the keyboard's internal plate is mounted with soft material (gaskets) rather than screws, creating a more flexible and cushioned typing feel, often resulting in a deeper, less harsh sound, like typing on a cloud instead of a hard surface.
Tri-mode Connectivity (Bluetooth/2.4GHz/Type-C)
This gives you options: Bluetooth for connecting to multiple devices easily, 2.4GHz wireless for a more stable connection with a dedicated dongle (often preferred for gaming), and wired Type-C for charging and zero-latency use. It's like having three different ways to drive your car, each for a different situation.
Hot-Swappable Sockets
This feature lets you pull out and replace the mechanical switches (the parts under the keycaps that register your presses) without soldering. It's like being able to change the tires on your car yourself, letting you customize the typing feel and sound whenever you want.
75% Layout with Knob
A 75% layout is a compact design that keeps most essential keys (like function row, arrow keys, and some navigation keys) while saving desk space. The added knob is super handy for quickly adjusting volume or RGB brightness without digging through software or using awkward key combos.
Alternatives
If you need full software customization on macOS or prefer a metal chassis, look for keyboards that explicitly mention QMK/VIA support or a full aluminum build.
