Replaced my cheaper Colgate electric toothbrush with this one. I have no regrets. It’s quiet, which is great for not waking up the Mrs while in the ensuite. The pressure sensor is really accurate and seems to be assisting in providing a great clean. Love the app.

I should have just purchased the basic version and paid a quarter of the price.
This one doesnt give anywhere as good a clean as the basic series (with a floss action brush head) does.
The app is SO unhelpful! All it does is remind you to reduce the pressure when brushing.... even if you apply the pressure for just 1 second. It has no added benefit whatsoever.
Do yourself a favour and Dont buy this.

This toothbrush looks and feels exactly like the high end quality that I would expect. It has a stylish and unique look to it. I am glad I went for the black.

When I purchased this toothbrush I was worried that it was going to very technical and difficult to use with all the features that it has. However it was so easy to use and it greatly improved my dental hygiene routine. The vibration was good and the feel with great. I was very impressed with hardcover travel case which also looks very stylish and can easily be popped into your bag or pocket if you wish to use on the go or are away from home. The battery is also very efficient and holds charge which is a plus especially if your like me and on the go a lot.I would definitely recommend this toothbrush for anyone who is looking to improve their overall dental hygiene routine. This is an excellent buy and great value

5.0 out of 5 stars Excellent brushing experience
Reviewed in the United Kingdom on 15 October 2023

The toothbrush exceeded my expectations. It is very easy to use with a simple design that is quite advanced in technology. You can really feel the difference after brushing with it as it leaves your teeth feeling incredibly clean. There are four type of cleaning smart modes, which you can change at a tap of a button. So far in using it, I feel it has a good battery life and I use it twice daily. It also comes with a travel case for the handle which feels a bit flimsy, however the brush head holder was of a good quality and standard. I feel the pressure sensor is an important feature of the toothbrush, which has given me a better brushing experience. I have only just downloaded the app, which has additional features to motivate good oral cleaning habits. I would highly recommend this toothbrush to anyone, as I have really noticed the difference since using it on my teeth.

4.0 out of 5 stars Great electric toothbrush
Reviewed in the United Kingdom on 12 October 2023
Verified Purchase
The toothbrush has a smart look about it and looks like it is expensive. This toothbrush has 4 settings which is great but it is hard to see / figure out which one you are on unless you are in the app. This toothbrush really did get my teeth clean and the app is a smart little feature. I liked the pressure sensor to see if you are brushing too hard. There is also a brush head reminder on the actual toothbrush which is good. It felt good in my hand to use and felt robust like it would last a long time. The battery lasted really well. The heads are not the normal oral B heads I am used to but they seemed like they were quality heads although a little on the expensive side. The toothbrush Overall this is a really good toothbrush and I would recommend.

5.0 out of 5 stars Great upgrade
Reviewed in the United Kingdom on 13 October 2023

This pack comes with the toothbrush, 1 head, a charger and separate cases for the brush and head.
I had an old Braun toothbrush before this and bought this as an upgrade, this toothbrush is much quieter and smoother when in use.
The instructions ask you to download the Oral B app which allows you to track your brushes and also set challenges, I have set myself the Plaque Fighter challenge which is 28 days and reminds me to floss and use mouthwash after every time. I then also reveiw rewards for goals I have met.
The toothbrush itself is very smooth and minimal, it looks great in my black bathroom!
Alrhough it only comes with 1 head in the pack it’s easy to find replacements, the toothbrush will alert you to when the head needs changing which is so clever!
I have been using this everyday since it arrived 4 days ago and the battery is still over half way full!
It’s really simple to set up, the app allows you to choose your favourite colour for the light around the bottom of the head, I chose pink. When I brush this light changes to green when good amount of pressure is used and red when too much pressure is used, then when you finish 2 minutes of brushing it celebrates with a rainbow!
I can tell a massive difference from using this the last 4 days, my teeth feel cleaner already and it’s great to have a reminder to floss which is something I always forget, this is very important to me for healthier teeth!
I look forward to brushing my teeth everyday now!

5.0 out of 5 stars Oral B iO4 is a stylish winner
Reviewed in the United Kingdom on 12 October 2023
Verified Purchase
When I ordered this product, I was impressed by the look of the iO4 online, but in the flesh its actually a very good looking piece of kit. It's matt black, with an ergonomic fit to the hand and has a middle white panel that showcases the on off button and the bluetooth connectivity.

The package arrives with a travel pack (not sure it's necessary, I'd just put the stuff in my wash bag) and a head for the brush which clicks into place nicely. The instruction booklet is clear and easy to read.

I've used other Oral B products before and this one feels much more sturdy and built to last. It is a solid weight in your hand and the button clicks nicely.

The charger unit is as standard for the Oral B range and has a long enough wire to fit round any products that may be left out on bathroom worktops.

The brush head is medium-hard bristles - my gums bled a little the first time I used it, but have been fine since. It gives a beautiful clean and leaves your mout feeling very clean afterwards although you should bear in mind you are paying for this - £80 + so it should be a good product for that. The option is there also to connect to your phone via the Oral B app. I'm really not that bothered by finding out my 'brushing dat' whatever that is, I really wanted a good brush quality, sturdy product that would last for a long time and this certainly delivers.

It's a high quality product that I would recommend to others but would point out that cheaper options are available so it's your call whether you feel this works for you.

I'd also add it feels a lot easier to clean than other electric toothbrushes - there are fewer cracks and creases so a wash in the shower works well
