## Description

Review: Fantastic keyboard - Overall well thought out and very well functioning. Great connectivity with the dongle. Great switches, slim, light, customizable, love it. Only negative is that the layout has a cramped arrow key cluster and lacks a home cluster. If they'd make it a 75% layout and add some shine through backlight it would be the perfect keyboard.
Review: Slim, Light weight and Portable - I’m really impressed with this keyboard! The slim, lightweight design makes it perfect for my desk and easy to carry around. It connects seamlessly through Bluetooth, 2.4GHz, or USB-C, and switching between devices is effortless. The battery life is phenomenal — I’ve been using it for weeks and haven’t had to recharge once. I brought this due to the portability, using it at the workplace. Typing feels smooth and quiet, ideal for working in shared spaces. It’s also great that it supports both Mac and Windows layouts right out of the box. The only small downsides are the lack of backlighting and the shallow key travel — not a big deal for casual office use. Overall, this is an excellent keyboard for the price. It feels premium, performs reliably, and offers incredible value compared to more expensive models. Highly recommend it for anyone needing a versatile, portable wireless keyboard!
