I bought a few, but I haven't used them yet (baby is due July 2). At this point, I prefer the AIO that I got from them than the pockets... but that might just be because I don't really like pockets at all.
I have the AI2s and I like them, they fit well etc. the only thing is I needed to by don't fleece liners because the hemp inserts absorb slowly and the pee would leak. DH on the other hand hates them, because to him it's an extra step to put an insert in and he would rather have AIOs.

I love them. I have the bamboo inserts and use them for other pockets as well.
I did purchase an AIO, but it leaked on us, it seemed small so it may have just been a fit issue.
