I should have written this post AGES ago, but feel confident saying this this is the BEST after regular use for almost 6 months. This thing travels well as it can be rolled into a small size, is very durable, and completely lets me be hands free while I pump. I have the Medela pump and it's hard for me to hold both flanges with one hand. With this I never have to worry about them coming loose, and I can adjust the tightness all around. Whoever invented this just gets moms who need to pump! There isn't much of a learning curve for putting it on which is great too.
