The brushes seem good but please notice that the 2-pack only comes with 1 additional replacement head. I thought there would be an additional replacement head for each but instead there are only 3 total heads in the package. So my wife has a replacement head and I do not. I should have paid closer attention to the description and not assumed each brush comes with a replacement head. I think this 2-pack would make a lot more sense with 4 total heads. Just strange to call this a bundle if it is designed to be shared with two people but only one gets the extra brush head.

[This review was collected as part of a promotion.] This is a great toothbrush, with awesome features. The charging station is magnetic,and it has seven different settings to choose from depending on what type of cleaning you prefer. You can also connect it to your phone through the Oral-B app. It also includes a charging travel case which is a plus! Leaves my teeth and gums feeling very clean.

[This review was collected as part of a promotion.] I love this brush! It holds a charge for a very long time, and I love that it travels easily! The settings are great, and I love that there’s a timer on it. It’s lightweight, and I have no doubt the heads will last for a while! My mouth feels great!

[This review was collected as part of a promotion.] This is going to lengthy but heartfelt.... I was a diehard fan of a different brand of electric brushes for about 12 years (since they first became available). During this time not only did I love using mine, but also gave several as gifts to family and friends. So for a layman I have a decent frame of reference. Was very cautious about Oral-B brush and not ready to love it. Initially I was off to a rocky start because accidentally selected Japanese as preferred language (stupid of me, so be VERY careful when you first turn on the brush). The language is easy to change, but for that to happen you need to understand what the brush is saying. After several futile attempts at constructive dialog with my new gadget and a few Youtube videos I managed to change it to English (also, do you now how it bruises the ego when your toothbrush speaks Japanese and you do not?). Now to the brush itself. Really high quality tool. Once you get used to it, very easy to operate. The brush-head itself is somewhat bulkier than what I am used to, but not too much so. I tried it on different settings and find all of them comfortable. Cleans beautifully, mouth feels really fresh. Like the timers and especially like that after two minutes the brush does not shut off. Often there are a few places to go over once more, so now you can brush as long as you prefer. Like the pressure indicator light A LOT, because I have a tendency to push harder than necessary. However I would prefer if it was located lower on the handle, since it is hard to look at without a mirror. But still, very useful feature. The charger is nice and sleek, but for me was somewhat confusing in the beginning. First attempted to use it upside down. There are three tiny protrusions on the bottom of the charger which match perfectly notches on the bottom of the brush. Figured it out almost right away, but would be great to have some clear indication which side should be up. Minor thing, I agree. Holds charge for a loooooong time, great battery life. Very handy travel case, but I think it would be better to have a compartment in it for a charger as well (for extended trips). All in all, very, VERY happy with this brush (surprised myself). Smart tool, but not to make owner feel intellectually inferior. Oh, also, it would be great if two buttons on the handle had distinctly different surfaces, so you could use them blindly. It takes getting used to and if you pull the brush out of the mouth to turn it off, it might spay the mirror. You get used to the location of the buttons after a few days, but still, would be great to have them different from the get-go. In short, LOVE this brush, really enjoy how it cleans and the rest of the useful features. Very happy with it, extremely glad I convinced myself to give it a try.

[This review was collected as part of a promotion.] I really like this product. I’ve never seen this before on shelves but this one is pretty cool! I love it! I was super excited to try it. I would definitely recommend this to anyone looking for a new toothbrush.

Just got this stupid thing - have 3 graduate degrees and thing won’t just brush. If lucky can get to do tongue 30 seconds. No manual, instructional videos, or online manuals. It is a stupid toothbrush and they made it unworkable. My god it’s a toothbrush that needs a manual.

I bought the iO Series 9 a few days ago…and I love it. However, there is no brush head holder and the brush will NOT stand up on it’s own…so not very sanitary if you like to take the brush head off after each use like I do to avoid any mold or mildew between the 2 parts.

My husband bought a two pack for us. It is great at cleaning our teeth, no complaints there. For me, the toothbrush head is too big. It’s 2-3 times the diameter of my Philips toothbrush head, and as a result, I cannot close my mouth the same way and end up with toothpaste and saliva down my brush and on my fingers. It’s so annoying that I’m considering going back to my old Philips brush. Painful considering the price of this brush.

[This review was collected as part of a promotion.] Right up front the basic brushing is great, but this is supposed to be a premium device that goes beyond basic brushing and this is where it misses. First off, the brush has no memory to upload your brushing coverage after the fact. Who wants to have to always use your phone and brush to gain those insights. Maybe my phone is charging elsewhere... maybe I'm using my brush in the shower. So the feature wasn't really thought through for the price point and really offers very little benefit given the limitations. Additionally, the travel case should support USB charging to eliminate the need to carry a separate charger. These may seem like small details, but that is what should distinguish a premium device from the entry level.

[This review was collected as part of a promotion.] Very smart little toothbrush! I like the convenient charging case. It did take a little bit to figure out, but once I did it is amazing. I love the different colors that you can change the lights to on it. All in all it is a great product!
