Oral-B iO Ultimate Clean Electric Toothbrush Head, Twisted & Angled Bristles for Deeper Plaque Removal, Pack of 4 Toothbrush Heads, White

Terrible brushes. Cut up my gums causing swollen gums and infection. The brush head is huge compared to the brushes that came with my tooth brush. The back of the brush hits your other teeth while trying to brush.

Item as described in the listing!

Works not good with keeping away tartar build up.

the 8x10/16x20, 4 pack was the cheapest (7.50 per head) i could find for IO ultimate clean on amazon. not sure what 8x10/16x20, means but it is the correct product. the packaging I received was written in German but they are the right heads. FYI if you dont know, the little icons on the bottom do not mean they are a different type of head. they are just simple identifying markers (there are 12) so if you share a bathroom or a handle you know whose head is whose. way to go Oral-B! thinking outside of the box, and even promoting sharing and not promoting more sales!

They fit perfectly in my oral B IO.

At the time of writing this review, the cost for the 4 replacement heads were cheaper than all other competitors, while still being genuine. Would definitely buy from again.

These are nice, expensive though.

They clean really well and I like them and they’re still gentle enough to use with every brushing but they have a chemical smell that kind of leaves a weird taste in your mouth for a while after you use them. I hope this goes away.

My husband bought it for me for Christmas and just love it

I love this electric toothbrush. These replacement heads were a great deal to replace the old ones. I would recommend
