I bought later my engine because my old engine over time is broken. The delivery came püntklich. The engine is the same as the original was the fountain purchase it. Only the connector is different ---> unfortunately a bit too large and thus a bit cumbersome at the outlet, the original was smaller and more manageable. It is also a pity that the light oil coating on the metal dissolves with the time and I do not know which oil to regrease would be suitable for the motor and is not dangerous for the cat. Ansonten it works without any problems and is also very quiet. If he is sometimes louder, then only at the 2nd or 3rd day and only so because the amount of water ---> has decreased so again time for water changes.
