Isabella ★★★★★ Oct 21, 2026

Switching between my laptop and tablet is seamless with the Bluetooth 5.2—just a quick key combo, and I'm typing on the other device. The slim profile feels surprisingly sturdy, and the 75% layout saves desk space without missing essential keys.

Richard ★★★★☆ Oct 23, 2026

I was a little worried the 75% layout would feel cramped, but the ultra-slim profile actually makes it comfortable to rest my wrists. The Bluetooth 5.2 connected instantly to my iPad, and the battery life has been solid so far. Only wish the backlighting was a touch brighter for working in a dim roo

The 2.4 GHz dongle is my go-to connection and it's been rock solid with zero lag, which is more than I can say for my last keyboard. Only real gripe is the ultra-slim keys take a day to get used to if you're coming from a standard profile. Once you adjust, the 75% layout is perfect for a tidy desk.
