No problem! My model was unimom allegro. 1 set comes with one bottle, 1 set parts and the pump. U have to buy additional bottel and the parts. 1 set of pump i bought at $150 from pupsik. The bottle i bought from mothercare i dont remember how much. But the pump is definately very convenient coz its small. To me its less noise as well. Im working as well. I did my pumping mostly at my desk.
