Over All Rating Reviews : I have one of the older models of Sonicare called Advance. It came with larger brushheads and, until now, these types of smaller brushheads did not fit the older Sonicare Advance.
Apparently, Sonicare decided to stop manufacturing the old Advance brushheads and made these smaller and tilted brusheads compatible with the Advance models. To the Sonicare Advance users that is good news because these brusheads are far superior to the older large Advance brusheads.
Theses heads are ergonomically tilted and smaller so it can reach the backtooth and hard-to-reach areas far more easily and dextrously. Although these brushheads vibrate at the same rate as the older Advance brusheads, they vibrate much more vigorously and create a far more intense sonic pulse and brushing action. The result is a substantially cleaner teeth. I would say these clean about 20% better than the old Advance brusheads, which were not exactly deficient.
Unlike the older Advance brusheahds, which required replacement every 6 months, these need to be replaced every 3 months.
If you are a Sonic Advance owner, do not hesistate to replace your old brusheads with these.
