The Oral-B iO2 electric toothbrush offers premium iO performance at a fraction of the price
The Oral-B iO2 is the newest and cheapest electric toothbrush in the brand's flagship iO range. That lineup culminates in the outrageously expensive Oral-B iO10 – which costs either £400 or £800, depending on whether any offers are available.
With the iO2, the proposition is simple: take the superior, near-silent magnetic cleaning technology that makes the iO range so good, but bring the price down by stripping away most of the sillier bells and whistles of the more expensive electric toothbrushes in the series. This is an iO-series brush pared back to the bare essentials, focusing on the thing that actually matters: getting your teeth properly clean.
After months of testing, I'm convinced the iO2 is not only the best-value brush in the iO lineup, but one of the most sensible electric toothbrushes you can spend your money on. Nobody needs an AI brushing coach or 101 polishing modes. This does all the simple things well.
How I tested
Without wanting to seem too obvious, I used this like a toothbrush. I squeezed a pea-sized amount of toothpaste on the bristly end of the Oral-B iO2 and cleaned my teeth, morning and night. I tested the Oral-B iO2 for six weeks, swapping out my usual Philips Sonicare 9900 – though I do still pick up the Suri electric toothbrush whenever I travel. Throughout my testing, I paid attention to these key criteria:
Cleaning performance: I used the iO2 twice a day, paying close attention to the smoothness of the tooth surface and along the gumline. I used all three brushing modes to see if there were any noticeable differences in the results.
Battery life and charging: I used the iO2 normally, brushing twice daily to measure how long a single charge lasts. Once it was fully depleted, I timed how long it took to get back to 100 per cent, to test Oral-B's claims.
Design and comfort: I considered the ergonomics and build quality of the brush, how comfortable and secure the handle felt to hold and move around, especially when wet.
Why you can trust IndyBest reviews
As a tech journalist who has tested more electric toothbrushes than I care to admit, I've become an expert in dental hygiene. I've spent four years swapping between brushes, evaluating everything from the most basic models to the smartest, app-connected gadgets from Oral-B and Philips. My focus is on separating the genuinely useful innovations from the marketing gimmicks, with a view to identifying the features that actually contribute to a better, healthier clean.
