Review on Beewarm Replacement Pump for 84oz/2.5L Cat Water Fountain - Ultra Quiet, Long Life Span, 6ft USB Power Cable - DIY (Water Pump) by Angel Young

This pump works in my cat fountain, although it doesn't actually fit in the "ring shaped" area at the bottom of the fountain. The pump body is slightly larger than the original, but all I had to do was insert the tube into the top of the fountain (tightly), then lower everything to the bottom and let the suction cups do their thing. It is very quiet and pumps better than the original. I didn't think I'd care about the extra LED light, but I love it! The fountain glows blue, a great night light. Very happy with this product and this seller.
