Bought this replace a unit with a failed internal pump.  Work Great right out the box.
I pump the water out through my dirt floor basement window into watering cans for our garden.
The nice thing is that is has a filter in the water tank that filters the water before it goes into the pump.  That makes the water cleaner and less stress on the pump.  The pump only needs to work  every few hours for few minutes while it empties the tank.  Again, less stress on the pump.
Worth every penny to have a well designed unit!
