Reviews
I love how thin and light this keyboard feels on my desk. Typing on the low profile switches is smooth and quiet enough for late night work. The battery lasts forever even with the lights on. Switching between my laptop and tablet happens instantly.
The customizable keys through VIA make my workflow so much faster. I set up macros for my favorite apps in minutes. Bluetooth connection stays reliable all day. The only thing is I wish the RGB had more brightness options but overall I am happy.
Carrying this keyboard in my bag for travel is easy because of its slim size. The adjustable angles help my wrists feel better during long coding sessions. Hot swap switches let me try different feels quickly. Great for both work and casual gaming.
