These ones are the best... look for promotional packs for a super price...
I highly recommend!!

Very high-quality heads, they leave the teeth really smoother and cleaner, as if you have just had a cleaning at the dentist. The bristles "hug" the tooth well and effectively clean between the teeth and along the gum line, without causing discomfort.

The wear indicator on the bristles (which changes color over time) helps you know when you need to replace them, which is very practical so you don’t forget. The 12-piece pack is economical and lasts for a long time, especially if the whole family uses them.

Top in its field and category is Oral-B ...
Anyone who doesn't use an electric toothbrush doesn't know what they're missing (!)
These particular heads, the cross action ones, are the best in terms of cleaning teeth better than other types of Oral-B heads (personal opinion after using and comparing both) ...
The teeth are spotless, as if they've just been cleaned by a dentist... of course, I always use the company's recommended floss as well!!
Do a search because the stores and the company offer good deals, advantageous in every way!!
Their use is highly recommended!!

much, much harder compared to the regular Cross Action. They reminded me in hardness of some no-name ones I had bought and threw away immediately. In this sense, I don't know if I got a counterfeit product because I read that one main characteristic of counterfeits is their hardness.

I made the purchase because this particular package has many heads as shown in the photo, but I received an envelope with 2 loose heads…..

The heads wear out very quickly in 5 brushing cycles and need replacement, the bristles have turned yellow!! Fortunately, the price was low!

For 10 years I used the precision, I got these for better ones but they are very hard and irritate the gums with the slightest contact.

My kids have been using it for several years, and the fact that they haven't changed this particular product says a lot... Very economical...

They do their job just fine! Completely satisfied. I have bought more expensive ones and there was no difference..!

It wears out very quickly, I would have been better off spending 5€ more and getting the better category

Perhaps the most economical package for anyone using this head (which provides exceptional cleaning).

In me only this specific replacement does the job in cleaning, so I consider it a one-way street in electric toothbrushes until today.

I will give it 4 stars because the brush is harder compared to what I have tried. Despite that, the result is okay.

No relation to a conventional toothbrush. Incredible feeling of cleanliness and much more effective against plaque/tartar. However, it wears out easily in case you have braces, etc. It needs replacement within a month, while normally it lasts up to 3 months.

The Cross action brushes are considered the best brushes from Oral-B and achieve the best cleaning compared to all other Oral-B brushes.
The only complaint I have, however, is that they are slightly harder than they should be, resulting in minimal irritation to the gums during the first week of use.
That's why, in my opinion, the golden mean in Oral-B brushes is the Precision Clean.
