This size is pretty good. I guess it depends on what you put in. I liked it for jeans and t-shirts, undershirts and long underwear. Sweaters were a bit big and bulky for it, except for light sweaters, and I'm not sure it compresses them enough anyway. The whole compression aspect of this product is a bit trumped up, but it certainly does restrain things in a way I found really helpful. There's something oddly satisfying about opening up a suitcase and seeing it all neatly organized. Is it worth $23 for each of these? Depends on how much you want that feeling, I guess. We bought too many and returned the ones we didn't open, because that is a lot of money, frankly. If I had to pick a price without knowing manufacturer's costs, marketing, etc., I'd say as a customer that $15-16 seems fair.
