Too soft! Does not transfer vibration properly
These were the cheapest that were available . I thought I would give them a try . Bristles are clear stacked monofilament and IMO are very flimsy in comparison to the real Sonic Care heads . You need a certain degree of stiffness to transfer the sonic vibration to the tips of the fibers . I don’t think it’s there and they hinder performance . If you apply pressure the brushtip will just squash out on a flat surface . The real ones or better generics you cannot . Next time I will avoid clear fibers like the plague .  They aren’t bad, but they aren’t good either . I tell it like it is sorry. This is a regular toothbrush head on a mechanized head . No bueno . Not complete transfer of vibration sorry guys .
