iMore found that circular keycaps disrupt tactile guidance and increase missed keystrokes for touch typists, while the fixed low typing angle prevents ergonomic adjustment. TechGearLab measured an average operation force of 60.56 gf with quiet scissor switches that reduce acoustic disruption in shared spaces. Pack Hacker noted that certified post-consumer recycled plastic construction feels sturdy despite the budget price point and provides up to three years of battery life from two AAA cells. The device fits travelers seeking portability and sustainability, but touch typists requiring precise key alignment or users needing adjustable wrist angles should look elsewhere.

TweakTown found that the Gateron Red Nano linear switches deliver a smooth, creamy typing feel with acoustics that are quiet and rattle-free. The keyboard features an impressive 4000mAh battery providing up to 1200 hours of runtime when backlighting is turned off, alongside a hot-swappable rotary knob module for customizable system control. However, TweakTown pointed out a lack of per-key lighting adjustments, with side accents serving only cosmetic purposes, and noted the knob is wobbly and can pop off easily. This compact 75% layout suits users seeking portability and multi-platform compatibility but may disappoint those requiring precise dial feedback or granular lighting customization.
