Being quite sensitive to electric toothbrushes, this one seems to clean brilliantly and also seems to be gentle on my gums which was something that I needed.I chose the io4 as the blurb on the page said that it had a pressure sensor and this seems to work well as it directs me to clean better than I was before. It leaves my teeth sparkling and they seem to look that bit better after only a short use.The charging is good and it comes with its own little stand that keeps it upright whilst charging. The two pin adaptor included needs a shaver type adaptor as I haven't got any power in my bathroom at all, but this isn't too much hassle, just remember to get one if you need it.It looks really good too, and I'd definitely go for this again.

5.0 out of 5 stars Base unit became faulty but was replaced easily

B. · 13 May 2024

Comes with base unit for charging, a toothbrush handle and toothbrush head.Great toothbrush for the price with three modes on it. (I think)Once turned on it has a sensor which changes colour if you use too much pressure on gums.It also lets you know when you have been using it for enough time.You can also download an app and sync toothbrush with it but I haven’t used that option yet.This unit stopped holding its charge after a month or so but it was easily fixed.Bolo let me send it for repair at no cost to me. They sent me a postage label to a service centre.It was returned within 8 working days and it looks like they replaced the main unit (handle).Excellent service as always.My wife has same toothbrush and has had it for over a year with no problems.

It's shocking. Don't buy this it's a complete con. The battery life is absolutely useless and doesn't even slowly die. It just dies instantly mid clean.

4.0 out of 5 stars Great toothbrush would recommend

j. · 12 October 2023

The toothbrush has a very smart look about it I like the plain white toothbrushes compared with coloured ones it feels more clean. This toothbrush has 4 settings which is a great feature but it is hard to see and figure out which setting you are on, on the toothbrush, you have to feel your way if you don’t have the app to hand. It has a useful change in vibration after 2 min of cleaning. 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 great. It felt good in my hand and easy 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. The boys in my house like the coloured black version but I like the white the best.

5.0 out of 5 stars Oral-B iO4 Electric Toothbrush

C. · 18 October 2023

The Oral-B iO4 Electric Toothbrush is a more affordable option in the iO series and offers great brushing results. The modern design and quiet motor make it comfortable to use. The toothbrush is equipped with smart features such as Bluetooth connectivity, timer, and pressure sensor.However, the brush heads specific to the iO series are more expensive. Additionally the iO4 lacks fast charging and the OLED display present in higher-end versions. Nonetheless it’s still a worthy option considering its superb cleaning power.Overall, The Oral-B iO4 Electric Toothbrush is a premium product that delivers excellent value for its price. It’s a great choice if you’re looking for a high-quality electric toothbrush with smart features.

5.0 out of 5 stars High quality toothbrush

The quality of this toothbrush is at the highest level. It cleans very thoroughly because, first of all, it tells you how to brush your teeth properly with smart pressure sensor. The toothbrush can be easily connected to the application via Bluetooth, where you can choose your favourite colour. It is handy and easy to use. It works quite quietly. It has 4 smart modes: daily clean, sensitive, super sensitive and whitening. The package also includes user manuals, brush head and charger. I am 100% satisfied and I recommend this purchase to everyone.

Just been using the irrigator and heads. Absolutely useless. Even the heads won’t stay on but fly off and let water go everywhere. A waste of money. Toothbrush is fine, but oh Oral B you could do better

5.0 out of 5 stars Super Clean

s. · 17 October 2023

I upgraded my and my family’s toothbrushes from the standard Oral-B electric to these new iO models and it has been such a great decision!The new iO models are so much better at giving you that clean mouth feel, so much so it almost feels like you’ve been at the dentist for a professional clean!Looks wise these toothbrushes are sleek and have a lovely matt finish to them, which makes them easy to grip and they also look great in the bathroom.The iO4 model comes with various features, including being able to change the brush style to sensitive or whitening. The brush also has an LED indicator telling you if you are applying too much, too little, or just the right amount of pressure. This had certainly been eye-opening to me after discovering I brush too lightly and should be applying more pressure! There is also a built-in timer indicator that vibrates to let you know when every 30 seconds pass to move onto the next part of your mouth (2 minutes brushing in total).These added features are a great bonus, but to be honest, the main reason I bought this and the main reason I’d recommend it us due to the cleaning performance. At the end of the day that is the most important function of a toothbrush and this Oral-B iO 4 is the best in the market I believe. Definitely worthy of the upgrade from older Oral-B models as I have discovered.
