The pump and filter set work great, and have done wonders cleaning up my pond. However, there are several issues the detract from the product.First, the fountain attachment does not include any kind of ball joint or adjustment, which every other similar device I have owned has included. This means you need to find a level spot at the correct depth to place the pump, which is not an easy task - I ended up just hooking the pump up to my waterfall and leaving out the fountain part. Not a surprise, but it was a little disappointing.Second, the filter sometime floats. There doesn't seem to be much rhyme or reason, as it will run fine for days with the filter staying on the bottom, then one day I will go out to find it floating at the surface (with the pump still running). Regardless of the reason for the spontaneous flotation, some built-in ballast would remedy the situation. Placing a rock on top of the filter has helped, but even that occasionally fails to keep the filter on the bottom.Other than those two issues, though, I have been happy with the performance of the pump and filter.
