I have the left shift button and spacebar, both help really tie the entire keyboard together. I plan on getting the badges and eeveelutions later.
Love the directional keys, remind me a lot of time I spent playing on my GBC as a kid. They were really easy to put on.
The keycaps came just as advertised in the pictures. They feel amazing on my keyboard and I can barely tell them apart from the keys that I took off. I ordered the set without the english letters, mainly because I spent a lot of time in the Ruins of Alph as a kid and the extra letters just felt too cluttered for my own taste.
I've never really thought about changing the keys on my keyboard until i saw these online. I had to get them and I could not be happier with them. When I first installed them, i was worried about typing since they letters are small/dark (and the awesome unown shine through), but only a day or two, i adapted to the new key images and helps me touch type quicker.
These Avatar Keycaps are very well made and look amazing. I used the 4 elements as the arrow keys, Aang for ESC and Appa for the F13 key I have on the keyboard. I suggest using the caps on switches that have an RGB diffuser to make the caps pop.
