Oral-B - iO Ultimate Clean Replacement Heads, Black - 4 Pieces

Replacement heads fit perfectly and are very well-priced.

Have been using my io9 for about a year and its made a big difference on my dental hygiene. I cant live without it and these toothbrush heads last about as long as a regular toothbrush does.

Love them

Fair value

These are well made, but pricey.

This product feels significantly different from the head that came with the brush. It takes longer for my teeth to feel cleaned and the brush was hard. I bought because of the value but next time I would rather spend more to get the product. It does fit though

Works perfect

too quick and all good

Great value!

these arent always easy to find - great price to have extras around the house when we need them!
