I just love the idea of this wireless breast pump by Willow that I first read about from Engadget. No wires or tubes at all, and they recommend charging just once a day. Whenever I had my twins, I wrongly assumed that all pumps were essentially hands-free but soon found my pump to be a literal ball-and-chain that I grew to loathe! My only concerns would be effectiveness and bag size (shown in 4 oz). But for the convenience I would probably be happy to swap out bags if this task ever falls to me again!
So my question is only if they will rent or only sell? They look to be available spring 2017.
