Bests & Worsts Reviews from Amazon

this was the only cat water-fountain that i could find on Amazon that had an AUTO SHUT-OFF for when the water gets too low - so the motor doesn't burn out if the bowl runs dry... couldn't wait to try the AUTO SHUT-OFF, so we filled it up to a little over the MINIMUM mark on the viewing window and plugged it in... the blue LED came on and it started pumping water in a little fountain out the top of the pump and we started taking water out with a small ladle... and sure enough as soon as the water got below the MINIMUM mark on the side viewing window the blue light went out and it started BLINKING RED - AND THE PUMP STOPPED PUMPING, protecting it from burning out from pumping while dry... very slick - 3 filters, cleaning brushes, plastic mat, they've thought of everything, you just have to remember to clean the pump every 2 weeks... perhaps they'll build in a timer in future renditions that will blink the light GREEN when it needs to be cleaned... after it has been going for a week, our cat has finally started drinking from it - however after only ONE WEEK the amount of water coming out of the pump has dropped about in half... pump already clogged? filter already clogged? will add more when i find out - if it is the filter, this could be expensive replacing filters every week...
