The eyecups are as described, arrived well packaged. The delivery time is too long. There are original parts, there are no problems with the accuracy of fit. The eyecups fit without play in the guide rails and lock with the low-dimensional hook. The pressure of the locking hook is very weak, so for example when you carrying the camera hanging over his shoulder, constantly there is a danger when stuck to clothing, etc. to lose the eye cup. Countermeasure of mine is the additional application of a strip of double-sided tape between eyecup and camera body.
