Oral-B - iO Ultimate Clean Replacement Heads - 4 Count (Pack of 1)

Works great. Great quality and great price.

If you own this iO toothbrush, you’ll see that replacement heads are extraordinary expensive. I pick this one because it was the best value for my buck. And my teeth feel incredibly squeaky clean.

Correct head for the IO

Fit well. A bit pricey but it’s worth it.
