"technology for teeth"
I bought the Elite compact heads on the recommendation of my dental hygienist. The smaller head seems to fit into the angles of my teeth better. I like the Sonicare products in general.

"Sonicare"
Absolutely the best toothbrush on the market. I use compact head replacement brushes because I have braces and the smaller surface works better than the standard head for cleaning orthodontic appliances. I find it necessary to replace the brush every four months, as I must brush after each meal, usually three times a day.

"compact head works better for me"
I like this compact head brush. I've often felt awkwardness maneuvering regular size brush. I guess it was too big for my mouth. Now using compact head brush, and I think I'm being able to brush my teeth better.

"Compact=Small, Excellent for difficult to reach back teeth"
Before ordering, read the product description. Previous reviews indicate many did not see "Compact" in the product description. Compact means Small. It's not another synonym for portability. For the standard, large brush, search for the Standard brush head.
Sample compact brush head came with my Sonicare 2pack brush kit (2 std, 1 compact). When I got around to using it, I found it excellent for reaching the back teeth. My hygienist scolds me for not keeping the back teeth clean but it's not easy to do with the standard size heads unless one has more space. Oral B brushes are the right size for me and Colgate are too large if that helps readers get an idea. Can't find the compact version in stores easily so Amazon is a great resource. The subscription plan was to save money but since it took a while to process online, I accidentally ended up with a double order. So if you subscribe, wait a day before trying again.
Recyling tip: a hammer knocks off the super strong magnets when the brush head is ready for trash. Knock off in a box because once it goes flying, it's difficult to locate. Box walls will rebound the sucker so you can pick up the loose item. Keep away from children (tendency to swallow which results in nasty hospital bill) and any credit cards or stuff easily demagnetized. Makes for great magnet crafts.

"Great Product"
I have owned my Sonicare product for three years and love it. I decided to try the compact head replacement brushes and love them. They see mto do a better job cleaning all of the areas better than the standard brushes.
