Obviously did a lot of research on the new head, the brush is extremely soft on the gums

I like that they are in individual sealed package. They are the exact replacement brush I need.

These are expensive so olny but when on sale. Sam's has best price. They also don't last as long as the ones for the old model.

Good price when they are on instant saving but they don't seem to hold up too well it seems like they just manage to last about 3 weeks

Like new again!

Great price for product.

Im sure it deserves the 5 star, I love the oral B system, however, just because it’s an oral B product does not mean it fits all oral B toothbrush bases. I had to return it for the correct fitting brush attachments.

Why did they come out with a different type of toothbrush that doesn't fit on my original style electric brush. I bought these and they do not fit on my handle.

These are probably very good...unfortunately for me, I purchased the wrong ones and do not fit my Oral-B. After I got these home, I opened and threw away the packaging and placed the new brushes in a drawer for future use. Eventually took one out to use, realizing then I had purchased the wrong ones. Expensive lesson learned.

I bought the six pack of the ultimate clean refills. Each one (on my 3rd refill now) has only lasted less than 30 days before the blue had disappeared from the head! What the heck?! I’ve always ordered the plaque removal style prior with each lasting well beyond 30 days. Please exchange these and replace with the plaque ones. Can’t afford to be replacing a head every month. By the way, I LOVE my iO 7 brush! Hygienist has a positive comment on my brushing each time I go for my 6 month cleaning. 70 years old and proud of my teeth and Oral B, except for these ultimate clean refills. I have included pics too.
