I have only use mine a handful of time , but so far , so good . fit be true to description -lrb- although leg opening be a \* little \* small . should not be a issue unless you LO have really chunky thigh . the snug opening do help to contain accident though . my lo can flood a diaper , but this hold one void without leak , and it even contain a very mushy poop . we be still very early in learn to use the potty , but my LO do notice a difference when he go in this as oppose to go in he cloth diaper or disposable . he actually tell I he go instead of simply go about he business . I probably will not venture to use these outside the house until he be a little further along in the process though .
