I took it on an international trip for 5 days last week. I used 3 cubes and 2 small bags for extra toiletries. I was able to fit 10 outfits, 3 pajamas, and 5 bathing suits with coverups and personal items. I think it did the job, but I am not a fan of the tightening straps a when I stuffed one a little too much the zipper split open. I have had packing cubes in the past and they seemed a little more durable. I do like the options and colors with this one so the jury is still out.
