And it isn't a quick adjustment you can make. Picture changing your wiggle baby and realizing the diaper is too loose or too tight around their thighs. Normal snap adjusters you just snap or unsnap. If your even the least bit talented you can do it while the diaper is still on the baby. This diaper you would need to take it off the child and readjust. And if you have two in diapers, good luck.
And they are so small. Much smaller than the average cloth diaper. I had about 20 of these diapers in my stash and they were the first to go.
