These have worked well so far for my daughter's potty training.  I have to say they don't absorb all the pee during accidents, but they are easy for her to pull up and down.  We use them in combination with plastic pants, and together they do manage to contain the spill.  I like that she can feel that she's wet, and so can we, unlike with the disposable pullups.  My daughter is a skinny and slightly petite 26 month old, and the 2T fits her great.
