Work well for Medium+ stiffness
Most of the non-Phillips replacement heads have bristled that are quite soft and less dense than the originals. Although these are listed as 'Kids Soft' they are stiffer than 3 other brands I've tried. That's a good thing, by the way. Bristles are not quite the density or feel of originals, but they get the job done. Only a big difference if you're used to DiamondClean.
