We have always used snappi's with our prefolds but then I got some inserts that made the diapers too bulky for the snappi's to fit. These are the perfect alternative - so glad I found them! They are easy to use and stay in place effortlessly.
Perfect for our cloth diapering needs! These diaper fasteners are great since I sometimes need one on each hip of her diaper rather than one (3-prong), now that my baby is getting bigger.
As baby has grown, we prefer these Boingo fasteners as compared to the Snappis. As compared to Snappis, the Boingos don't create any tension across baby's lower abdomen and are more forgiving if the diaper isn't perfectly centered under baby's bottom. We've purchased all of our Boingo fasteners from Sweetbottoms and have had no issue -- they arrive quickly, as expected and are priced well.
I use the Boingo for prefolds, and it does a great job. The teeth are super sharp, though, so be careful!
Working great for me, and the kids like the star shape. I'm actually using it to fasten my old BumGenius Velcro diapers closed. The teeth catch in the fabric underneath the loop material, but I do take special care to ensure its hooked properly.
