we just started using them about 2 weeks ago. we have some concerns, the inserts have the same type of gel in them that is used in regular diapers and we h ave heard that this is not actually environmentally safe. also, in order to get the gel part out you have to rip the insert down the side and bottom which usually means touching either the pee or poop. sometimes it doesnt rip very cleanly and it the mess just kind of falls everywhere (sorry to be graphic). the plus is that the covers are really great and they fit well. we havent had any leaks. what were doing now is mostly just using the covers and putting cloth inserts in them. once in awhile we use the g diaper inserts. the other nice thing is that since your flushing everything there isnt the constant smell of diapers in your childs room or the bathroom (wherever you keep used diapers). if money is a problem, if youre just going to get the g diaper inserts, its more expensive than disposables.
