All three broke as did the last one, within 2 weeks!!
It is obvious that Lactona is no longer made by the same company. They have been a well respected company since the 70’s . The current brush heads broke in less than 2 weeks. I am a licensed dentist, Fellow of the Academy of General Dentistry, and do peer Review for scientific journal articles. I also give monthly lectures at Federally Qualified Community Health Centers.  This purchased does not even deserve the one star.
