It's very clear when comparing side by side these have far fewer bristles than the Pro Results Plaque Control that they have replaced. Please do your research and be sure you are aware that this is different than the older model.

These are no longer soft. The specifications on the sonicare store label these as "medium" but in-store purchases label the exact same C2 as soft. Either way, these are too hard now. No longer are they soft.

[This review was collected as part of a promotion.] I use my electric brush everyday, and it works great! My teeth have never felt cleaner….except when I get out of the dentist chair.

[This review was collected as part of a promotion.] I've been using this brush for over 7 weeks and I haven't noticed any reduction in tartar accumulation. I've had to use dental picks to remove it. On the plus side, it's a USB-rechargeable appliance which is good.

[This review was collected as part of a promotion.] After having tried other non-Philips attachments, I was pleasantly pleased at how well it both it the unit and my mouth. This C2 Optimal Plague Control head smartly moved around my mouth with ease, fitting well in the "hard to reach" places.

Good brushes that fits my Phillips Powerhead.

These are factory brand heads so they work as expected.

Bigger head and works great.

Interchanagable with sonic elec tooth brushes

Excellent fits my Sonicare.
