Gro Baby biodegradable inserts?

We use the Gro Baby diapering system and I'm just wondering who out there has tried the bio inserts and what you think about them? Absorbant? Better than a disposable? LO generally sleeps the night in a disposable diaper to make night time changing easier. We also use them when we are going to be out of the house a long time. I am just wondering if these are a good solution to not using the disposables. I would really like to get away from using them! I guess I'm not quite brave enough to use the cloth diapers at night (though I haven't really tried it much). I will be returning part time to work soon and am thinking these might ease daddy and grandma (whom he will be staying with while I'm at work) into the diaper routine a little easier. Thank you!
