It broke faster than any toothbrush, meaning it didn't last much longer than a month. Good for whitening and gentle. It doesn't even penetrate between the teeth, not even as a joke.

The mistake was mine for not noticing that the shape of the brush is not round but oval. Other than that, it is a decent brush, value for money.

Compared to other heads, I have not been satisfied. It wears out relatively quickly and maybe I am clumsy (especially in the morning), but when you try to clean it, you end up filling the place with droplets. There are clearly better ones.

Basically, I received 4 packages of 2. They are the original spare parts so everything is as I expected.

This is what I always buy. Objectively, everything is the same with Oral B, there is nothing specific to evaluate. It is the correct replacement for my toothbrush.

At first, I was thinking of throwing it away. This plastic in the center makes it extremely difficult to handle the toothbrush to the point where I can't brush my teeth. I wouldn't recommend it. The plain head without the plastic is excellent and more economical.

I have tried the regular brush and the double brush from Oral B. Obviously, I will compare it to the regular one and I will say that it has a slightly different feeling because of this purple rubber in the center. However, I'm not sure how much it helps, I feel like it pushes the brush away from the point I would like. Maybe it has a purpose and meaning, but I haven't understood it yet. Otherwise, it's fine, quality and cleanliness worthy of the Oral B name.
