JJC Z9 Eye Cup Eyepiece, Camera Viewfinder Eyecup for Nikon Z9, Soft Silicone 360 Rotating Extension Oval Design, Replace Nikon DK-33 Eye Cup

Works well with glasses, slightly harder to take off but doable. No complaints overall

I always wanted a contoured eyepiece for my Z9, but couldn't justify the cost for "just a piece of rubber to look through." How wrong I was! After losing the OEM eye cup while out on safari, I took the opportunity to upgrade once I got home. This new eye cup is INFINITELY better than the standard eye cup - for one thing it contours to the shape of your face, helping you quickly seat the camera and get a much better view with no light intrusion on the already-bright viewfinder. It's an extremely comfortable fit for extended photo sessions, and can be rotated for use with either eye. BONUS: the larger size of this eye cup keeps the camera away from my face and my nose no longer smudges the screen constantly. Nice! I give this eye cup a very strong recommendation, even if you haven't lost your OEM eye cover.

As others mentioned, very firm. It is flexible to the hands but when I press it against my face to seal light out, it's very uncomfortable. I have a narrow head which doesn't help things. Someone with a fuller face would probably have less discomfort. It does attach easily to the Z9 and doesn't inhibit the function of the monitor. The silicon rotates well around the eye piece so that you can shoot in portrait or landscape without any difficulty. All-in-all it seems well built, just to stiff.

Seems to be good quality but time will tell. So far really like it.
