We purchased this for my wife to use to make her pumping experience easier - and it does exactly what it advertises.  It holds everything in place so that pumping is a hands-free experience.  For those moms who need it - the product is definitely highly recommended.  Because of the design, it works with multiple pump brands - really good so that you don't need to buy a brand-specific model.  It is also VERY adjustable - so it would work for women of many sizes - just follow the sizing guide in the description.
