I use this pump for my second home since I've had the same model in my main home for 10 years (without a flaw). The pump works well, but mine arrived looking like a soccer team all took turns with free kicks before delivery. The unit's housing has a 1 1/2 inch chip broken off the cover, but I decided to glue the chip back rather than return the product. The pump works well, but water remains in the holding tank after cycling, so keep the unit from freezing and watch for mold growth. I add bleach to my every so often.
