Works great. There is an added safety "time out" feature that will shut off 120vac to the pump if the top level sensor is not activated within a certain time. This safety "time out"" is adjustable by turning a potentiometer on the circuit board inside the unit. The maximum time that I was able to set was 17minutes on my unit. The instruction manual does not tell you this, you have to call JBJ customer service. This is to prevent your pump from running dry. I had to modify mine because I needed longer time for my solenoid to stay on longer in order to fill my resevoir.
