This diaper is almost identical to the Nikki's cover, but it doesn't have the flaps in the front and back for you to tuck the prefold into. Since our daughter is older and wiggly, we stopped using the snappi with our prefolds and this diaper cover isn't as nice.
I have been trying several with double leg gussets because our 1 year old started leaking out of lots of diapers. This one did an okay job but was not one of my favorites. The snaps on the rise sometimes came apart as I put it on her but and it did leak more than the other double leg gussets that we tried. Getting the pad (we use Flip's Stay dry) in was sometimes a circus because of the style but it does fit. I preferred their best bottoms much much more.
You can't beat this cover for the price. The fabric is nice, not stiff... and the gussets are very good. It is definitely one of our main go-to diaper covers. The only change I would make is adding an additional snap at the waist (over to the side, like Kissalauv's has). But overall this is a great cover.
