I bought the black on black keycap because it reminds me of my little guy (as if there isn't enough dog hair everywhere, lol). The packaging is fun but not super clearly labeled as I ordered one for myself and a different one for a friend and had to open the entire thing to know which was which. After fiddling with a couple different positions, I settled on having the paw print keycap in place of Function so I can more easily play/pause/forward my music.
My friend was very happy with the white and gray (her dog's color), so I would definitely recommend for fellow animal lovers!
I use this as esc, and the soft pad of the beans makes it easy to orient myself on the top row by feel. Touching typing the numbers row is still slow for me, but this keycap has helped me improve.
Squishy toe beans make push it over the top. The black paw with black toe beans have good contrast. I feel like these were designed by someone with a black cat.
Fits on pretty much any of my keys. I use it mainly for the escape key and occasionally the up arrow key. The sound is nice and the soft silicon paw pads are always purr-fect to the touch.
