a very useful gadget! i don't have a room at work, where i can relax and pump in privacy and comfort. that's where my minivan comes in! i sit in the back seat turn on calming music and pump. and, of course, none of it would be possible without this great adapter!!!! it's long enough to stretch all the way to the back of a van. if you're in that line of work where there's no conditions for pumping (supermarkets, restaurants, etc.), this product is just right for you! i highly recommend it!!!!!!!!!
