The 4.0 has been a FANTASTIC buy for me. Please note I did pick this up in the seconds sale so if you see some imperfections in my photos, it was a second product. I've only noticed the snaps are a little close to the seam on the closure and that one of the inserts wasn't quite sewn together all the way in one spot.
My first test of the 4.0, I put it on my son (who is heavy wetting & breastfed) who was at the time 2.5 months old. We were going into town for one of my doctors appointments. This excursion lasted 4-5 hours! We went the whole time without a diaper change. To my surprise we got home and there were NO leaks! This was the first car trip we'd made with cloth where we had no leaks at all. TWO thumbs up in my department.
I do own a 3.0, it didn't work so well when my son was younger for some reason, but as he's gotten less chubby and longer it is working better now. I'm glad the 4.0 has upgraded to snaps, I prefer snaps since I don't have to worry about aplix snagging other dipes in the wash or the loss of stickiness. The 4.0 is also larger, which is good for me since my boy is already 15+ lbs. I want him to be able to stay in his one size diapers for longer.
On to the pics!
The bumGenius 4.0 comes with the classic bumGenius adjustable insert & a doubler.
Outside of the diaper
Insert at its largest setting (this is pretty long!)
Medium (which is what I have it set at for my son)
and Small
Stuffed & ready to go (this is how I store it)
And snapped up in the settings for my son's size
If I was starting my diaper collection all over again, I'd definitely add some more 4.0's to my stash. It's a great diaper for overnight or long trips! I really like how this diaper comes with inserts that work great with it already so I don't have to figure out what to buy to go with it.
