Looks like I'm one of few who likes them! Both of my boys wear them and haven't ever leaked through during the day. For nights we just put them in a size up. They are $13.69 for a case so it helps us keep the cost per month down. The pros for me: inexpensive, velcro tabs that are big, and stretchy sides that are wide.
I don't like Huggies because the sides don't pull down far enough and they leak out the sides. I never had a leak with Overnights though, but they are shaped differently. I like Pampers but they are too much for as many as we need. I don't like Luvs because the sticky tape never stays where it should.
Buy one of the small packages and try them out. You might be surprised! My friend who refused to buy anything but Pampers has switched and loves them as well.
