|Personally, I wouldn't worry too much about it...
Yes, the first batch of OS bamboo diapers had a problem with the binding, but ME replaced (and is still replacing) them all, which is how I ended up with a brand new set of diapers after a full year of use. It's true that the bamboo diapers have not been fully tested yet as they have been on the market for only a year and a bit, but I guess I would see how they actually hold up before worrying about it.
So far very little people seem to have had problems with them. After a year of use, they seem to be going strong. Mine were good as new, apart from the binding (well, they were stained, but that's because of blueberry season, not ME) and I dry them in the dryer. People that use the Sandy's don't seem to have any problem with the bamboo either. So I wouldn't want to discourage people from buying bamboo, because I personally feel that they are well worth it for their softness, their thinness and the environmental factor.
