This was my first GMK keycap set and I am extremely satisfied. The quality of the letters is amazing, they are extremely clear and stand out super well, I love the texture of the keycaps and they also have really nice acoustics as well as very good coverage for any layout.
I appreciate the katakana sublegending as it's nice to have something other than the usual querty printing. I ordered this as a gift for a friend and they loved it!
