Excellent product

Yosvany Hernandez MoraApril 2, 2026✓ Verified purchase

I’ve been using this electric toothbrush for a few weeks now, and I’m honestly very impressed. It leaves my teeth feeling extremely clean, almost like I just came back from a dental cleaning. The brushing power is strong but still gentle on the gums. I especially like the built-in timer, which helps me brush for the full recommended two minutes. The pressure sensor is also a great feature because it lets me know if I’m brushing too hard. Read more

Good value

I've been using these replacement heads for over a week, and so far I'm pleased with them. I can't notice much difference between these and the name-brand replacement brushes. They attach easily and seem secure, and the bristles are holding up well so far. Read more

Not perfect fit

We ordered them as replacement for our Oral B electric toothbrush . They do not fit firmly as they are a bit off. Read more

Great replacements (even got extra)!

I have used an Oral-B toothbrush for a very long time and have stuck to their branded replacement brush heads. However, these can be expensive so I decided to try a generic replacement. Overall, I would say that I have been pleased with the exception of noticing that this brush head is a little bit smaller in circumference and a little bit softer than my typical brush head (I typically use the floss action). That is not to say that it does not clean your teeth well but more that you may have to move it slightly more than you have in the past. If you have a black toothbrush base, you'll love the 8 black brush heads; however, if you have a white base like I do, you may end up sticking with the white brush heads as the contrast in color looks a little odd (although it does not affect the performance). Each replacement brush head comes with a little colored circle on the bottom that is helpful if more than one person uses the same toothbrush and you need to distinguish whose brush head is whose. Finally, I'm not sure why but I ordered a 14-pack and received 16 so that was a nice bonus and other reviewers have said they also received 16. Overall these are good brush heads and I would probably buy them again as they are a cheaper replacement than the typical Oral B brushes and seem to do the trick. Read more
