Promaster Canon EB (EOS) Eye Cup

It snaps into place on my Canon body with a satisfying click and doesn't wobble at all, which makes framing shots easier. For a simple replacement part, the rubber feels just as durable as the original one that came with the camera.

I was worried a generic replacement wouldn't fit snugly, but this one clicks right into place on my Canon body. The rubber feels a bit firmer than the original, which actually keeps it from slipping off in my bag. Exactly what I needed to replace the lost one.

My old one had gone missing after a shoot, and this replacement fits just as snugly as the factory piece—no wobble at all when I press my eye to the viewfinder. The rubber feels a bit stiffer than the original, but it blocks stray light well enough that I stopped squinting outdoors.
