I LOVE my Bum-Ware diaper. The wahm is great, and very very fast. It usually only took a couple days after ordering to receive it! They are very trim and fit well. Good diaper for daycare and very daddy friendly.
Now, I know many people also LOVE them, but I do have two criticisms... First, mine are lined with flannel. The flannel gets very stiff when air dried or dried in the dryer. I hear Izzabella with do fleece if you ask - I wish I had done that! Second, they aren't as absorbant for my dd (we have the snap in soaker). Each child is different, but my dd can only go max 2 hours in this dipe. So it isn't a good choice for us to go out in... but it is a very trim choice for home! I don't know if it would be different if we had the true AIO.
Overall, I think Bum-Ware are fantastic, affordable, and great AIOs!
