My expectations were not high based on others' reviews, but I had a small flooding problem in our defunct dishwasher and had to pump out the tub. It took about three minutes with this pump and my 18V DeWalt drill (though I had to change the battery in midstream, but that was my fault for not starting with the fully-charged spare). I read the instructions carefully and lubricated the pump with a few drops of vegetable oil before starting, which freed it up nicely. Cleaned it out with clear water when I finished and packed it all back up in the box for next time -- the little plastic reel for the hoses is a neat touch. All in all, for what I paid for it, and for what I needed it for, it performed like a champ.
