Good fit, works well
Bought it now that Canon no longer keeps it in stock in my locality.The pair of them work as excellent replacements on my EOS 760D.

Good product
Got it because I’m now using eyeglasses.Good quality product for non- Nikon brand. It took a little effort to get this eye-cup on the viewfinder ring, but once fitted it stays attached.No instructions included, so check online for video instructions on how to install the actual Nikon DK-19 eyecup.

Works but inconsistent
I bought the 2 piece pack, which arrived on time and looked fine when opened. However, one piece fit perfectly on my camera body while the other did not fit at all. So, I guess it's a chance you have to take which may or may not work.
