Currently it's a 1 star because it doesn't work correctly.
I need to start with the bad because that matters most since it makes the board unusable.
The "drift" others have mentioned is real. I didnt see it at first and thought maybe my board was fine. But on my second day using it, very often keys just dont do anything. The key works. Pressing it again makes it work. But while typing a sentence youll have almost every word mess up. And often a key will just stay pressed down even when you take your hands away from the board.
I have reached out to Moondrop who is sending me something they think will fix the issue. They called it a "hub issue". I will be leaving this review as is until the part arrives and the issue is fixed.
Edit: Moondrop has sent the updated hub. I have installed it and nothing has changed. The board still unusable. I have let Moondrop know and they have yet to respond. I will give them a week then I will reach back out about sending the unit back as it obviously does not work as a keyboard. If they don't respond I will contact my bank because at this point it wont even work as a keyboard.
