Review on KEDSUM 330GPH Ultra Quiet Submersible Pump With High Lift And Grounded Power Cord - Ideal For Fish Tanks, Ponds, Aquariums, Statuary, Hydroponics - Includes 3 Nozzles And 1500L/H Water Flow by David Ramirez

No shocks, no electrified water, good flow, and quiet. I have only had it for two weeks, but seems to be working well. A greater variety of adapters including a T would be nice so I could run multiple water features. Removing the plastic filter improves the water flow markedly. Mine did not come with a sponge filter. I only use it to run water features, not to run my pond filter. I have now been running it all summer, and it is still working fine for my small waterfall.
