Now, I use a nice blend of cloth diapers and disposable diapers, so I am not unused to how diapers work. The appeal of the G Diaper was that it was supposed to blend the best of both worlds - environmentally friendly and easy to use.
The cover has a plastic insert that snaps in. You then add the diaper part. It was a lot like fitting a maxipad into the diaper cover. At first I wasn't sure it would fit but it did. They fit well and didn't leak, neither when wet nor soiled.
They work exactly like they say. You pull out the dirty insert, and rip it apart, stir it up with the special rod and flush. This is all accurate. What I failed to really think about was ripping the guts of a dirty diaper apart. That was pretty gross.
G Diapers worked well, but we wound up just putting the dirty liners in the garbage. Though on their site it also recommends that you compost the soiled diapers.
Earlier versions of this diaper were not as favorably rated. They also have some great styles now.
