They work great!
My son loves his vibrating toothbrush and it needed a new head. We change the head out every time he is sick and he was just getting over Covid. The brush head is high quality, it doesn’t shed and fits perfectly. The cost per brush is excellent! We will definitely be purchasing again.

Perfect fit
Perfect fit for the toothbrush. We have a different brand of toothbrush (also from Amazon) but it has been discontinued. But these replacements fit perfectly.
