The Willow breast pump

Ni
So doing some research last night, i came across a breast pump that is new for spring 2017. The Willow, you can wear it in your bra and pump anywhere, its quiet and efficient and with only 3 main parts two of them being dishwasher safe pretty easy clean up. My thing is for $430 i can only pump 4oz at a time each side. Is it worth it? Would you buy it? It comes with both sides so it is a double pump.
