Much better than generic / Compatible

I am very satisfied with these brushes. They arrived quickly.
This amounts to 2 the unit thus cheaper than other brushes Oral-B for the same quality.

The brushes adapt very well to my toothbrush (Oral-B 5000).

Unlike generic, they hold very well (more or less 6 weeks) when I wear braces quickly making use toothbrushes. Cleaning is always perfect, does not attack the gums and is much more effective as compatible.
Moreover, they do not lose hair when they start to wear out.

Very good product I recommend
