I purchased this product thinking it was the compact head, because that was the picture item. But when I received the product I found it was the standard size head. I also discovered the product was priced $8 lower after I received the product.

I conducted Amazon, but received no response, other than to give me authorization to return the product. I was not offered an opportunity to exchange the product, nor even receive a refund for the difference in price.

Returning it was more of a hassle than it was worth, so I kept the brushes, but still I was disappointed. Based on previous experiences, I would have thought Amazon would have permitted me to exchange them, or at least offer me a credit for the difference in price.

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.

Life is good, smile :)

My husband an I both have Sonicare toothbrushes . They are wonderful. Once you use one there is no other.

I was very happy to find the standard size replacement heads here on Amazon, and at a very reasonable price. I often have trouble finding these in my local stores -- they always seem to be out of stock. Replacing the heads on the Sonicare toothbrush is super-easy... so ahead and buy a set of these, your teeth will thank you!

I always seem to have problems finding this product in stores. They are usually sold out. Ordering through Amazon.com I get them quickly.
