The user manual says this one can remain plugged up at all times. The battery burned out on my previous model because I kept it on the charger. There was no battery low indicator light on the previous model and I got tired of waking up to a dead toothbrush. This one says that the battery is protected from overcharging.

Purchased as a replacement for an older model. Very surprised at the difference. This model feels almost like an ultrasonic cleaning versus the vibrating action of the older model. Very pleased.

Hesitant to purchase because of cost at first. I have used Sonic and Oral B for years. Sometimes in the morning and the other in the evening. Finally bought these because of the features and we do like them even more than the previous ones. The ability to “play games” so to speak on where you brush and what concentration you are seeking is kind of neat. It was a little pricey so hopefully it lasts. We’ve have the others for probably 5 or more years.

Maintaining good dental health has always been a top priority for me however, as, I have gotten older and learned the correlation between mouth health and heart health, it has become an even higher priority. Over the years, I have tried numerous toothbrushes but none have impressed me as much as the Oral-B I/O series 5 rechargeable toothbrush dual pack. Let me share with you thy this toothbrush has become and essential part of my daily routine. First and foremost, the Oral-B I/O series 5 provides a superior cleaning experience that leaves my teeth feeling incredibly clean and fresh. The dual pack includes two toothbrushes, allowing me and my husband to enjoy the benefits together. The deep cleaning action of the tooth brush removes plaque effortlessly and ensure teeth receive a thorough cleaning, even in hard to reach places. One of the standard features that I absolutely love is the smart pressure sensor that alerts me when I'm applying too much pressure while brushing. This has been a game-changed for me, as I tend to a bit too enthusiastic with my brushing technique. Now, I can confidently maintain the right amount of pressure, protecting my gums from potential damage. Overall I'm really happy with this purchase. The change in how my teeth felt after brushing was immediate. I didn't even intend to make the purchase but I caught a great sale. We had an older model Oral B's (at least 6 years old). This upgrade was well worth the money.

So far, I am enjoying the education I get from using the app showing me which teeth I have not been brushing the correct way and which teeth were not getting enough attention. I always thought I was doing a good job, but I was not. My teeth feel cleaner and slick when I follow the directions.

My husband and I had electric toothbrushes that were many years old. Mine was an Oral B and his was a Phillips. We have really enjoyed the upgraded features. I especially like the sensitive setting. They are easy to clean.

I love this product. It cleans my teeth well and delivers all its promises.

I love this toothbrush. It feels like a massage on your teeth! I feel spoiled every time I use it. The charge lasts for about a week which is great. I love this toothbrush so much I bought them for all of my adult children and their spouses for Christmas!

Much quieter than my previous Oral-B, which is great. The shape makes it a little mor difficult with my clumsy hands to know what position it is in. The fact that it wants you to exert enough pressure to make the pressure light indicator to turn green, seems like a lot of unnecessary pressure. By the directions, you can't just brush, you must keep adequate pressure on the handle to trigger the green light. In all other aspects it is a great toothbrush.

Not sure if I got a defective one, going on 2 months the buttons didn’t want to work. To change functions. Had to return it. I replaced it, so let see if this one works longer.
