- May 2, 2023 Sales start
- Low-profile mechanical keyboard with a new 60% layout not previously available on unmarked models
- Prices range from $94.00-$104.00
- Hot-swappable
- Double-shot PBT keycap adopted
- Wireless connection in Japan is difficult because it is not available through authorized distributors in Japan and is not technically compliant.

- Personally, I would recommend the Q9 Plus with the split space bar.
