My friend swore by these bottles and convinced me to try them for my daughter. The hole is on the side of the teat instead of the top so you need to make sure you hold them a particular way. The theory behind them seemed fantastic however, my daughter had trouble getting any milk out of them she would suck and suck for ages and not be actually drinking anything.
They may work for some babies but for mine they were absolutely useless.
