    After several other fountains this one is the best.

    I had purchased a small desk-top fountain which I love - but the pump made a loud humming noise that was awful. So I found this little pump and bought it to replace the other one. And it is perfect!! Hardly any sound at all so I can hear the gurgle of the water - so peaceful!  Thank you so much!

    I am very satisfied with this product.It sits secure, doesn't move around at all, and works perfectly!! This was my last attempt and so glad I didn't give up. The steady flow without water flinging around everywhere is soothing. No noise to distract from that soothing sound.

    It's a tiny pump and wasn't sure till hooked it up and it works perfect and you can't hear it run at all. I am very pleased after a week of it running constantly. Recommended to buy!!

    I bought this for my daughter's small 1 gallon betta fish tank as a water circulator, it's been installed for about a month and is working great! you can easily break the circulator down when you need to clean the minerals out of it and it's quiet. It's very affordable and I have had no problems with it.

    I got this for a potted water garden that I built myself using a half-wine barrel. It has great flow and suction, perfect size for the pot. I occasionally have to clean muck off of the the intake to keep the suction going, but that's to be expected with the plants in the barrel. Great value! I'll be getting another one for the backyard when I start relandscaping that.
