The electric toothbrushes in Oral-B's new iO range are the most expensive you'll find, so can the performance justify the price?
We ran the Oral-B iO Series 7 (£400) through a series of tough lab tests to see how well it removes plaque, how long the battery lasts between charges and how comfortable it feels to use.
Read on to discover more about Oral-B's newest release, or go straight to our full Oral-B iO Series 7 electric toothbrush review.
At £400, the iO Series 7 jumps straight to the top of Oral-B's electric toothbrush price range. But what do you get for your money? The specs on the Oral-B iO Series 7 electric toothbrush include:
If you want to see how it stacks up against electric toothbrushes from brands such as Philips Sonicare and Colgate, check out all of our electric toothbrush reviews.
One downside to the Oral-B iO range is that it's not compatible with the current range of Oral-B toothbrush heads, such as Cross Action and Sensi UltraThin. You will need to buy iO-specific brush heads. Electric brush heads aren't particularly cheap anyway, but the new iO ones will really empty your wallet.
There are two types available: Ultimate Clean and Gentle Care. These will set you back between £13 and £15 per head if you buy them at full price.
A pack of four iO Ultimate Clean brush heads, which should cover you for a year, typically costs £54 at Boots, while a pack of four Oral-B Cross Action brush heads at the same retailer is just £18. Paying three times as much for them is probably going to be a fairly bitter pill to swallow for most Oral-B acolytes.
Oral-B iO brush heads are currently on offer at Bootsand you can expect to find them discounted at different retailers throughout the year. Make sure to shop around before picking up replacements.
