"Do not buy this keyboard. I bought it for 50 USD and I so regret it. To switch layers, for example between number keys and function keys, you have to TOGGLE layers. And how do you toggle them? By pressing Fn+1 and holding for 5 seconds!!! And to switch back, you need to hold again for 5 seconds. This is absolutely the worst keyboard design ever and I wish the person who came up with this design slips on a few stray keycaps and falls and gets impaled on the outemu switches this keyboard uses" https://www.reddit.com/r/MechanicalKeyboards/comments/98eb0q/what_is_the_motospeed_ck62/e9d0tka/
