These covers are an awesome value, if you need to be a little frugal in your diapering these covers and some prefolds or flats are the way to go. My only negative comments: the hook and loop is kinda coming undone but not bad enough to make them unusable (after 8 months of use), and like all velcro it is scratchy.
We use this cover for our 2 year old son, and we like it pretty well. It is very trustworthy, and he can make it overnight with this cover and a bamboo prefold. My only complaint is that it is hard to get the fit right. The crotch is narrow, so the prefold pokes sometimes. I have to get it tighter around his waist than I would like in order for it to fit well around his legs. He doesn't seem to mind, and it doesn't leave marks, so I guess that isn't a big deal.
These are quite wonderful, especially for the price. We have several different adjustable size diaper covers, and this is on of my favorites. They are sturdy, thick fabric that washes well. I like the narrow velcro, as I find that the wider velcro sometimes digs into our baby's tummy. The gussets are great. The only thing I wish was that they had pockets to tuck the diapers into. I would buy again, as they are half the price of my next favorite cover.
I bought this cover hoping that I could use it around the house and upon using it for a week it's my go to cover. I use it over fitteds right now but since I am so pleased with it I am going to order some flats and some imagine prefolds. I got this in the pink with the aplix and it is holding up beautifully. The velcro is sticky and despite changing some VERY wet diapers this cover holds it all in and I've had no leaks. I can't wait to order some more!
