We have been using them for about 2 years now and I have to say, the qualify has definitely declined from our first son two years ago to second, who is 7mo. They leave a lot of lint on our baby now than I remember with our first. But you can't beat the price. In addition you get target discounts and gift cards. So for an infant who demands a diaper change immediately after peeing even a drop, these are good. They stay on even on my super active babies.
We just switched or toddler to pullups. And he loves the two designs. It even has an indicator in the shape of a star or stop light, which we can tell him that it gets damaged if he pees in the diapers. It is sort of a good motivator for him.
