So good!
Typing this review on this keyboard right now, actually. Showed up super fast, went together easily and the instructions were very clear.

Nice Little Board, But...
Had a lot of fun building the board, and I enjoy using it. One thing I'd like to say about the build experience is that my board did not come with the reset switch. I looked high and low through the packaging, but it was nowhere. Instead of having to go and order a single reset switch and wait a few days for shipping, I chose to take one off one of my other boards. A bit annoying, but I was okay. I feel a little too lazy to order a single switch for my other board now, and I just think it would've been nice if I had received one, like I was supposed to. All in all, it took a bit away from the build experience, but I still enjoyed it.
