Perfect little pump for my outdoor water features. The bottom has 3 suction cups so it securely stays put and the pump has an adjustable flow dial so you can use it with a trickle effect or a bit stronger to actually pump through a fountain. The top has 2 different adapters for lines and mine fit perfectly with a larger hose. I ran mine for quite a bit in the sink to test and it stayed cool and once primed, pretty consistent in the water flow. It was easy to use and took less than a minute to get it attached, plugged in and adjusted. Note: this is not a powerful pump but would be fine in an aquarium or as I'm using it for - a smaller water feature. So far, it is doing it's job well and I'm happy with the purchase.
