“It is an amazing keyboard. One thing, I don’t like that there is no battery indicator for this version so that I don’t when I need to charge it before it die out.”

4 owner reviews
“very compact, build quality is great, and I don't even feel any latency when using the keyboard wireless.”
“The only "zmk" support is from the launcher itself and its missing most of the ZMK features. For example Combos!”
