I bought a few of these during a seconds sale and I am enjoying them. No leaks and no problems. They're easy to stuff and the rise snaps stay put. I'm not using the microfiber inserts since I can't seem to get them clean, but that's all microfiber and not specific to Bum Genius.
Update - 8 months: They are still on the smallest rise setting. These are the go to nap-time diapers since she has been primarily sleeping on her stomach for the past few months. Our other pockets leak when she is on her belly.
