Excellent compact keyboard
This keyboard is a dream to type on, the Gateron low-profile mechanical switches have a satisfying tactility. I use it wirelessly for both my Mac and Windows PC, and switching between them is seamless. The compact 75% layout is ideal for saving desk space without losing essential keys. Plus, the Black color looks very sleek.
★★★★★
Super flexible connectivity
Being able to switch between 2.4 GHz for gaming and Bluetooth for my tablet is incredibly useful. Setup for all three modes was quick and painless.
★★★★★
Perfect size
The 75% layout is ideal for my small desk, without sacrificing too many keys.
★★☆☆☆
Battery life disappointing
The stated battery life of up to 73 hours is not what I'm experiencing. I have to recharge this keyboard almost daily, even with the RGB backlight off. It's quite inconvenient for a wireless device.
