I didn't expect to like these as much as I did. I prefer one size covers and snaps. However, the velcro is quick, super tough, and has held up great (been using for six months and there's no wear at all)! Double gussets make them fit snug. If the diaper is super soaked, it will leak around the velcro, but that has more to do with me needing to change her sooner and less to do with the diaper's quality.
