Tested and Proven

In an independent test conducted in August 2004, the vacuum level inside various brands of bottles was assessed and compared to the BornFree™ feeding system.
This is the first time this type of test has been conducted.

(Since small babies will find a vacuum of -10 or more very uncomfortable, you can see why babies find it so difficult to feed from bottles that create negative pressure as high as -49).
The results clearly showed that BornFree™ had the lowest negative pressure, making it the most comfortable way for your baby to feed.
