I really really wanted to like these cost effective covers and they just wouldn't work, no matter what I did. They don't stay on, they don't fit well at all, which is crazy when the fitteds fit well so I guess the design is different for the covers. maybe snap ones would stay on better, but the hook and loop just sucks on the hook and loop ones. even if you get them to stay on (i resorted to pining them on one day) they still leak like crazy. maybe a different shaped baby would work in them, but my chubby lo just couldn't use the covers. I really like the Dappi pinless cloth diapers and was suprised by how little these have in common. By contrast these don't work well, leak often and the large which is suppose to be 22-35lbs hardly fits my 24lb son. My son also continuously tries to take these off, which is a comfort issue that he does with the gerber wrap type covers also, but not with kushies or proraps. After being so impressed and thrilled about the pinless diapers I was really let down by these covers. With this one you get what you pay for, they are cheap, but to have workable diapers covers from these you would to do some serious modifications.
