Query: Did not fit my sink. Leaked.

The hose connecting the unit to the sink had a head that was too big. I got an adapter which fit both components, but then once I hooked it up the whole thing started squirting water all over the kitchen. There was no solving this problem so I tried to return the thing. Their customer service didn't respond to me for weeks, but finally they did take it back and even paid for shipping. So at least that was nice enough.
