I bought this pump to repair the water fountain for my cat: it adapts well.
As against it is less powerful than the original pump and remains noisy compared to my other water fountain.
The quality is average, but I do not expect miracles for the price.

Embarrassing detail in my case: the transformer is integrated into the pump, so it can not detach the plug from the pump.
For assembly, I had to pass the cable through a hole, which was possible with the old pump was equipped with an external transformer, but is no longer possible with this pump powered directly 220V. This detail could be anticipated by analyzing the photos because the product is perfectly confirms photos.
