The power cable for the pump was a bit to short and I called to inquire if there was a longer one The answer was yes but it's out of stock. I'm expecting s call as to when this will be available. Everyone was helpful. The pump looks sturdy and is easy to install.

I was nervous to order this after seeing the negative reviews. I waited for over a week before posting this so I could get full sense of the product. If you expect this backup battery to power your fountain all night long I can see why you would be disappointed. What this is really good at is ensuring your fountain runs several hours longer than it would have without it, and for me it seemed to amplify the performance. The fountain stream seemed stronger and started and ran during a lower light level than without it. (Cloudy days, early mornings and evenings) It worked perfectly for what I wanted it for, but it is not the same as the battery performance of solar landscape lighting. Overall I’m very happy with my purchase.

I purchased a solar pump for my fountain that I made. I'm so glad that I purchased this back up. Anytime the sun disappears the fountain stops, but it never stops with the battery backup! It serves it's purpose.

FYI, this is compatible with the “ Biling Solar Fountain Pump”. Works great!

I am putting it in a outside water fountain .but it has been raining for three days so not finished the project.
