Review: Jade pro - Recomiendo este sayo, los switches son god
Review: Best device for fast input - Works nice the switches sound nice and feel fast, good for games that need 1-3 key inputs. Keys I liked it worth the cost, sticks to tables good as it sits sturdy just that’s it gets loud sometimes but the RGB and the screen looked good. Was able to customize it though you can’t rotate the image weights light, good to take on the go. Has good durability is able to handle some hard pressure. Was very compatible for pc and laptops and works for the iPhone 15 and above not lower. The stability is also over all great. Software is easy to use though a bit confusing sometimes like to put custom images though it’s not hard to figure it out. Would recommend amazing price for a device like this.
