This is a great electric tooth brush with various settings. It’s quiet while it’s powerful at the same time. The biggest bonus for us was it being dual voltage (so we weee able to use it no matter what country we were traveling to and didn’t have to compromise on quality).

Love this toothbrush! Its like the dentists in relation to vibration and function , although I am not saying its a substitute for a good cleaning! It lights up to make sure you are using the correct amount of pressure , stays charged for 10-14 days and even shows a smiley face, Sad face Or frown on the handle as To whether you are brushing long enough! I would definitely recommend this and Walmart had the best deal! Its not the newest version but I didnt feel I needed the extra gizmos

Advertised as a io7 model. Is actually an io5. Still appears to be a very good item, but it is not the one reviewed and recommended by Consumer Reports magazine.

I purchased a toothbrush two months ago and while I can’t say that it has cleaned my teeth thoroughly as well as prevented tartar around my gums. I only SJgave it three stars because the brush heads are too big for my mouth, causing me to gag as well as the battery life. If the toothbrush is not in an upright position, it never goes to sleep if it’s laying down or if you continuously open up your drawer, it will still be on.

overall the tooth brushes are great, but i expected 1 white and 1 black. i opened the package and was surprised with 2 white instead.

Toothbrush does a satisfactory job, when it works! However, I can't recommend it. A few months after purchase, and after being fully charged, it won't hold it. As soon as I turned it on it, it will shut itself off with a blinking red light on and a 0% battery indication on the display. After returning it to the charger immediately, it won't do a thing; meaning it won't charge it at all. It has a two year warranty with the manufacturer. Doing some research online I've discovered that this is a common problem with this Oral B model. As a matter of fact, I've experienced the very same problem with another model a few years ago and it was replaced. I did give Oral B a change, even after having that experience. I did message them, but if you happen to have a PO Box, they won't deliver any replacements to you. So, this is my very expensive lesson: I won't buy another Oral B ever! I don't trust Oral B, at all.

I bought these for my husband and I for Christmas and his has already stopped working. Of course it can't be returned at this point. It's a lot of money to only work for a short period of time. I'm so disappointed.

Do you have the mouth of a giant? Or can you unhinge your jaw like a snake? If so, this toothbrush is for you! The head on it is so big, you’ll barely be able to clean your back molars. It’s twice the size of a Sonicare. The bristles are so hard, it’ll make your gums feel like they’re disintegrating. I cannot believe they tested this and had no people comment on how awful of a design it is. Not to mention they charge $300. It’s truly unbelievable. I’m hoping Sam’s takes it as a return.

Not happy. Bought first set great product second set white/black not same black and white screen settings different battery not as good. I was sent 7s I didnt order7s. Looked up 7s suppose to be sensitive says nothing that all features are different. Very disappointed. Actually alot of orders have had issues lately what's going on.

Oral B needs to recall these brushes. A design flaw with the brush head prevents proper air circulation and causes bacteria buildup. Search online to see this is a huge problem with the iO series. For such an "advanced" brush, they should have done more testing and fix the issue immediately.
