I agree that it doesn't look sturdy compared to others but I have had mine a few weeks and I do actually like them! They elastic isn't as tight so he never gets red marks from them and I haven't had a single leak even with naps. I am worried that the elastic won't last that long though.
I thought the same exact thing when I got ours. I was disappointed and even considered returning it. So glad I kept it though because we really like them now (and I have since bought a few more covers and inserts).
I use the organic flips too. Totally soft now (especially when I dry them in the dryer...not as much when I line dry them...but that's the nature of that). We've had them for 8+ months and the elastic is still good. I really like them.
