I used these on our vacation, and they were great!  I just unpacked the suitcase, and when we arrived at our destination I put these on the shelf, and we picked our clothes out of them every day.  Very easy to re-pack also.  Highly recommend.  1 set worked well for me and my husband.  I packed all of our clothes, and my shoes using all of the set.  They open up all the way, which I really like.  To pack them, just zip half way, and start loading up.  I rolled all our clothes, and it held my pants, shorts, and tops, an all of my husbands shorts and tops.
