Fits perfectly and doesn't interfere with any operation, including use with the magic keyboard.
I bought this because i wanted extra protection for my ipad because i use the magic keyboard. i was worried about if the case could work with the protection on my ipad, and it WORKS! you just have to remove the three dots on the lower half on fishskyn protector to expose the magnets :) i was so pleased with my purchase that i bought another one to protect my magic keyboard itself :-)
