These are replacement heads for my years old holder. They are great but be prepared for a long struggle to open the package. This latest replacement head does not have individual head covers so I opted to keep the bulky book size package. Wish I had kept the old covers....

With Sonicare, I find it hard to avoid "jack hammering" my teeth with the hard plastic shaft, tip and sides of the brush. I find this unpleasant (could possibly knock out some dental bonding) and happens regardless of the particular toothbrush type. It's just hard to maneuver.

Smaller head is better than the bigger ones.

The fit the toothbrush fine and bought on sale so it was a good purchase .

Not sure it really removes more plaque than the whitening brush heads.

Great Toothbrush. Love the different settings.

Make sure you get the soft bristle one, otherwise your Dentist will chew you out…

These are the only toothbrushes I use

Work great with my Phillips Sonicare toothbrush!

Haven't opened the package yet but pleased with the price.
