My BF's sister swears by them. She also decided to sew extra inserts, so wet diapers don't necessarily need to have the outer cover changed every time. She just went and bought the same type of material from the fabric store. She has said that they have held up very well, even with having to soak them. She doesn't use bleach though.. she uses a solution with Borax and I think vinegar, but I'm not too sure.
