Arrived, and works, but action is extremely violent on 12V. Sounds like a damper or spring is missing. In addition to this, the plunger distance is stated as 35mm when it's actually only 31mm. This is a significant issues for applications requiring precise activation distance. Finally, the return spring is very weak, and I needed to order much stronger springs for reliable operation in my application.
Strong and fast, works 12V and 24V
