do not buy unless you like spending per replacement head for the rest of the time u own it [SEP] yes it works well but the only replacement toothbrush heads that are available to buy online via amazon at least are around each in general you are supposed to replace toothbrushes every couple months so that is almost extortionpersonally i like toothbrush heads that have a little more weight to them as well these bristles are not soft to begin with but they end up that way with no rigid parts to do more cleaningnot worth it
