This is the one pump that has never let me down. I have had one replacement under the warranty in 8 years . Company very good at sending out fresh pumps quickly.  I learned that whatever pump you buy always have a backup just in case. Love the ease of use.  The long cord is handy, and the fact it easily fits in a sunk pond filter box is a plus. I have plenty of room for my bio materials and filtering medias. Two thumbs up...
