love this toothbrush, at first I was skeptical about buying it but so glad that i did. It brushes well ad so far I haven't had any problems , always pickup some of these replacements they are great! It's nice to be able to purchase the toothbrush and the replacements at the same place, I will continue to purchase the replacements as long as Sam's continues to carry.

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.

Good product, but too expensive for sams.

Replacement brush heads are priced right and the amount stretches through the year.

Perfect fit. Lets you know when to change it

I love these toothbrushes! They are just like what the dental hygienist use with bristles.

Very expensive and need replaced quickly.

It ok it fits.

Great price

Greeeat value for these iO replacement brushes. Much, much less expensive than at any other outlet.
