Product notes
AULA F99/F99 Pro Tri-mode Wireless Mechanical Keyboard RGB Hot Swappable Custom

Choose the AULA F99/F99 Pro when customizing and connection flexibility matter more than a new-condition purchase. Its tri-mode design supports Bluetooth, USB-C, and 2.4GHz, while the 8000mAh battery adds a concrete wireless-use detail. RGB backlighting, PBT keycaps, pre-lubed linear switches, and a gasket structure give it a distinctly customization-oriented setup. The limitation is its Certified - Refurbished condition, which makes it a different proposition from the new-condition IROK and S98 Pro. It suits a shopper comfortable with that condition and interested in adjusting the keyboard's feel and configuration over time.
Wireless RGB Hot Swappable Mechanical Keyboard 3 Layers 81 Keys Gaming Keyboard

The IROK Wireless RGB keyboard fits a shopper who wants an 81-key gaming keyboard with switch experimentation and a straightforward wireless setup. Its hot-swappable design supports 3-pin or 5-pin mechanical switches, and the three-layer silicone sound-absorbing construction is intended to reduce keystroke noise. A built-in battery supports cordless use. The limitation is that its connectivity is identified as wireless, while the AULA F99 explicitly lists Bluetooth, USB-C, and 2.4GHz choices. Pick the IROK when the 81-key format, hot-swap support, and lowest listed price lead the decision.
AULA S98 Pro Wireless Mechanical Keyboard with Screen & Knob Blue White

AULA S98 Pro is the fit for shoppers who want controls and information built into the keyboard experience. A screen supports customizable settings, while the knob adjusts functions, giving the layout a different focus from keyboards centered on switch changes. Its wireless format and blue-white design reinforce that screen-and-control use case. The limitation is also its focus: hot-swap support is specifically named for the AULA F99/F99 Pro and IROK, while S98 Pro centers on the screen, knob, and wireless connection. Choose S98 Pro when on-keyboard controls matter more than a switch-customization brief.
Keychron Q1 75% Custom Mechanical Keyboard - As-Is Spill Project

Keychron Q1 75% Custom Mechanical Keyboard is for a hands-on restoration, not a simple plug-in purchase. It powers on, connects to a PC, and registers input, but several switches are sticky or non-functional after a protein-shake spill. Its fully hot-swappable design allows 3-pin or 5-pin replacement, and the case and plate need deep cleaning. The wired, illuminated, plug-and-play setup defines the starting format. The limitation is substantial: used, As-Is / For Parts or Restoration condition makes switch replacement or cleaning part of the assignment. Choose it only when a 75% custom keyboard project is the point.
Final recommendation by use case
For the broadest connection choices alongside a customization path, choose the AULA F99/F99 Pro. Select the IROK keyboard when an 81-key wireless layout and the lowest listed price define the brief. Choose AULA S98 Pro if a screen and knob are the reason you are shopping. Reserve Keychron Q1 for a wired 75% restoration project, since the spill condition and sticky switches make repair part of the purchase. In short, prioritize connection modes, switch work, interface controls, or restoration first; the price table then shows how much that chosen direction costs.
