The bottom line: if your toothbrush is a Sonicare Advance, you are going to need replacement brush heads and that's reality. Both of my kids are using Advance and they should be replaced at lest every six months.

Like most of anything that's a Sonicare brand (there are exceptions) these are good quality products that last for the six months of twice-a-day daily use, as advertised. After that, you will need new brushes and Amazon has them while most other stores don't.

This paricular brand and compact size is very hard to find. If you own an older Sonicare and need brush replacements...this is the place to get them.

I have an older Sonicare and wasn't able to find any replacement heads for it locally; they were all for the newer model. I ordered these to try and thought that I could always send them back if they didn't work, but am happy to report that they work perfectly. I am very pleased with my purchase.

Thank you so much! I've had my Sonicare toothbrush since the first infomercial for it , you couldn't buy them in the stores yet. According to my dentist , I have a small mouth {my husband disagrees with this diagnoses!} so I need to use a smaller brush head which aren't very easy to find. Needless to say , I can always count on Amazon.com.. The price is very reasonable and transactions and shipping are always a breeze. It came in the mail in just four days! I'm a very happy customer! Thanks again,Debbie in Maryland

You did not make clearThat the heads came in compact and regular sizes . I recieved the compact size and am very unhappy with them!!!!!!!!!!!!!!
