Not perfect, but worked better for us than snappis
Snappis weren't working for my chubby baby and he seemed uncomfortable with them pulling so tightly across his lower abdomen (maybe he wasn't, but it made ME uncomfortable!). The Boingo fastener works pretty well, except when trying to pull it tight to attach, I really wish there was a loop or extra tab of some kind. I always end up reaching my fingers too close to the teeth. One time my baby initiated a roll just as I was trying to pull the fastener across and the teeth dug into my finger and tore some skin... ouch! Other than that one design flaw though, they do seem a lot more sensible than the Snappis, at least for us.
