[This review was collected as part of a promotion.] The OralB i05 toothbrush is an incredible new advancement on the way you brush your teeth. There are so many things and settings and tracking that this toothbrush does I recommend that you fully read the instructions a couple of times before you use it. First thing is the small tip. There is not that much space for paste but the amount of vibrating the brush makes surely stirs it up. What I do is put it on and then before turning on the brush spread the paste around on your teeth first because the vibrating is so much it will send it off your brush, especially if its not in your mouth first.There are multiple settings for intensity and sensitivity as well as whitening and all can be seen and changed very easily from the handle. I didn't notice much difference between the two intensity settings or the two sensitivity settings. The difference between the intense and sensitive felt like a less vibration mode. Now as far as how high tech this is. It times how long you spend brushing in each quadrant. It will pulse after 30 seconds to tell you to move on. It also can tell how much pressure you are putting on the brush and will light up red if its too hard.Once the time is up it will change multiple colors. The ring of colored lights is easy to see as well as what mode you re in while brushing. The app does take a little getting used to and requires more input if you like as it can track flossing, brushing your tongue and if your gums bleed. This is all stuff you would enter manually. As far as brushing on guided mode , you have to connect your phone via Bluetooth to your toothbrush. Imagine that ! your toothbrush has Bluetooth. After turning on the get started brushing you will see as set of upper and lower teeth. The toothbrush actually knows where in your mouth you are brushing and for how long and will turn the quadrant to white when its time to move. Afterwards you can track on the app days brushed, time, and collect medals for good dental care. It takes a little getting used to but now I find myself having to use it because I want to do good. After brushing my teeth I found they felt a lot cleaner than anything I had used before. It kind of felt like after a cleaning at the dentist. The multiple settings allowed me to gently do my gums for good gum care. What minor things I did not like but have nothing to do with the brushing experience is That the case it comes with is too short to allow you to put the brush away in without pulling off the head . There is no cover for the head if you want to leave it on the charger. The head goes on pretty snug and not that easy to pull off . Also I am surprised that such a high tech item that once the battery loses its ability to recharge that the whole thing needs to be thrown away. Other than that , which have no bearing on the brushing experience and the quality of the item I highly recommend this amazing toothbrush!!!!!

[This review was collected as part of a promotion.] The app feature is so great and it truly lets me know when I am applying too much pressure. After washing my teeth they feel so clean and even have a dentist clean feeling. I highly recommend and they also charge quickly. Love this

[This review was collected as part of a promotion.] My mouth feels amazingly clean. I was nervous when it mentioned bluetooth and an app because I'm not the most tech savvy, but completely easy set up. Fits great in my hands, travels well, easy charging, smooth in quiet in a way that doesn't vibrate my whole head.

[This review was collected as part of a promotion.] I've used a basic Oral-B electric toothbrush for years. I've had to replace it twice over the years and never pulled the trigger on the iO because of the price tag. I finally got one and regret not getting one sooner. My teeth feel even cleaner. I used the app a few times, it would be good for kids that need help brushing properly, but I didn't like having to watch my phone while I brushed. It also doesn't adapt to any missing teeth so you have to brush that area longer if using the app. The iO also lasts longer between charges.

[This review was collected as part of a promotion.] I’ve had dental problems for a long time, especially with staining and sensitivity. I’d been wary of trying an electric toothbrush because I was afraid it would bother my teeth but I was wrong! This brushes comfortably and makes my teeth feel so much cleaner! Over time I hope it will improve my stains too. Don’t hesitate to get this, you won’t regret it!

[This review was collected as part of a promotion.] I really like using this toothbrush, I have never had an electric one before, and now I will never go back! Using this toothbrush gave my whole mouth a fresh clean feeling that I have never really experienced before, unless I had gone to the dentist for a cleaning. I am really happy with this handle, and it is not too loud and pretty easy to use.

[This review was collected as part of a promotion.] This is the best toothbrush I have ever used so far! The noise is pretty quiet and the design, battery life and price are excellent. Honorable mention for the cleaning performance becasue my teeth have never felt better!

[This review was collected as part of a promotion.] I really like this oral b brush! It has a pressure sensor that lights up red when you apply too much pressure, and green when the pressure is appropriate. I do wish the modes were more intuitive and the quad pacer more clear when you're supposed to switch sides. Overall, I think this oral b did a better job cleaning my teeth than my current sonic toothbrush.
