Provides a very thorough cleaning and provides good information regarding your brushing

After brushing with this toothbrush I feel like I have been to the dentist for a professional cleaning. I am 70 years old and had some stains that come with age, this works wonders. Teeth discoloration can make you look older so I am loving this.

If you can afford them please get these toothbrushes it feels like I've left the dentist every time I use I absolutely love them and I was able to catch them on sale for 169!!!!! I rarely give 5 star reviews but trust me these are it!!

Great clean feeling after use. We love looking at the app that shows real time information as we brush. Takes a few weeks to become proficient.

Wish we could have bought this at our store instead of waiting for several weeks for it to be delivered.

These are great, they are definitely the IO Series 9 which is awesome and a smoking deal. They have the color screen and 7 cleaning settings. I believe this upgraded is isolated to this color combo only.

don't buy this toothbrush. this new housing design hold and traps water. it turns into mild. gross black sluggish gunk. almost impossible to get this to stay dry. must remove head and rinse thoroughly and hope it dries out.

Be carful when ordering the iO series 7 that is over $300.00. Make sure you get what you ordered. I had to return the much cheaper version of the iO they sent me.

The reason I purchased this model, even though I have another expensive Oral B toothbrush, was because I wanted a charging travel case. I was disappointed to find that instead of USB-C charging port, the case comes with a special plug and it's fitted for 110V. So in order to take this toothbrush abroad I need to bring this bulky plug AND an adapter for a different voltage. Ugh.

As others have mentioned, these are a good deal. These are actually IO 9 brushes with the associated modes and color displays. This has been this way for awhile as far as I can tell. We bought this same bundle two years ago and were impressed by the cleaning quality. They were flawless up until they recently got flaky and started turning off suddenly at 40-50% battery. This was workable, but suddenly one brush failed to turn on and will often get stuck at "Hello" while booting up. I am wondering if this is a firmware issue or there was some moisture intrusion. I looked back and we paid about 150 dollars for the pair a couple years ago through Sam's. I debated going Sonicare or other competitor this time, but I have already invested in quite a few IO brush heads. I also feel the oscillating head cleans well and did not want to take a risk with another brand. I also saw that these were on sale for slightly more than we paid two years ago. I had assumed that they would be identical, but there are some updates. The screen is much brighter now and appears to be LCD. The old IO9 from 2024 used an OLED which was dimmer, lower resolution, and had substantial PWM. This new model also has updated graphics and will not suffer from burn in like out old brushes have. This new model also has the benefit of flashing in the battery percentage more frequently before shutting off. The prior generation did not display the battery unless you placed it on the charger. This made it challenging to know when you needed to charge it. Biggest benefit of this unit over other brushes is the display. I rarely use the app connection and the other brushing modes, but I do appreciate being able to see how long I have been brushing. Also being able to see the battery percentage is nice. My main hope is that his updated model will be more durable than the prior version. That unit only lasted about two years before failing. I will say that I was pleasantly surprised at how easy it is to replace the battery. I took my old model apart and was happy that it is pretty user serviceable and just takes a 14500 lithium cell (AA sized) in a holder and can be swapped in a couple minutes. I did try another battery in that unit and could not get it to function normally, so it was something more than just the battery.
