I bought the Ebags packing cubes many years ago as soon as they were available and have used them on dozens of trips.  When I decided to order more packing cubes, I saw the AmazonBasics that had good reviews and thought I'd save a few bucks by ordering those.  BIG MISTAKE!  I can only imagine that the good reviews are from people that have never used packing cubes before and recognize it as a great idea.  The AmazonBasics don't come close to EBags as far as quality.  They are made of some cheap plasticky, noisy material as opposed to the strong, silky material of EBags.  I returned these ASAP and ordered EBags, even paying the expedited shipping so I could get these in time for our cruise.  Don't be fooled, it is worth a few extra bucks to get the EBags quality.
