I can try to answer any questions, but it doesn't seem like the 8bitdo Ultimate software is availible for download yet. Im not big into mechanical keyboards, this is actually my first, so I don't have much direct comparison experience to other keyboards.
but the buttons are big and f u n.
Factory battery was probably charged to a normal level and would've paired fine when opened if it'd been powered off. It was left powered on from the factory, which is not how it should've arrived. My experience is a valid criticism of a just-released rechargeable device and a QA issue. Where do you get off acting like I don't know how consumer electronics work because I'm criticizing bad QA?
I missed the word “on” when I first read your comment. I assume the commenter did as well. Until I reread, I thought you just said that it arrived in 2.4ghz mode. But you’re right. It should not have been switched on when you got it.
