Oral-B iO Series 9 Review | Trusted Reviews

Excellent review! And I’m not just saying that due to it having precisely what I was looking for today. A detailed break down of the differences between the iOs 7, 8 and, 9. The round charger has no protuberance. It does have a 2 pin power adapter, and supports 100-240v. It takes up to 3 hours to recharge the brushes on this stand.What’s more, it delivers an excellent clean, with three modes – Sensitive, Daily Clean and Whitening – that take you all the way from a softer brush that’s easy on the gums to a more intense polish that should help get rid of staining. Battery life, meanwhile, is exceptional; you’ll easily get through two weeks of brushing and probably three without a recharge. It’s the king of sensibly priced brushes and one of the easiest recommendations in the Oral-B range. Thanks to the iO Series 9’s frictionless magnetic drive, things were easier this time around and it feels more like brushing with a sonic brush. However, look at the brush head as it moves, and you get more energy and dynamic movement than with sonic models. As you go from one zone to the other, the LED board is lit, until all six lights are lit to indicate you’ve finished your brushing. The LEDs really are a guide to enable you to finish comprehensive and completely clean teeth. The iO10 works with the app. You are able to obtain real-time visual details on the phone display in case you wish, but the charging station assists you at the times your phone might not be with you. The Philips Sonicare 9900 Prestige is also easy to connect to your phone, but the app gives you finer control over brushing settings. Once you've set up the brush, you'll be able to change brushing mode and intensity separately, giving you a wealth of different options. We preferred the medium intensity in 'clean' mode, which gave a good clean while gliding smoothly over our teeth.

iO Series 9 vs Philips Sonicare 9900 Prestige: which Oral-B iO Series 9 vs Philips Sonicare 9900 Prestige: which

The best Oral-B electric toothbrushes to buy in 2023 1. Oral-B Vitality Pro: Best cheap Oral-B electric toothbrush Like the Oral-B iO Series 9, the Sonicare 9900 Prestige contains a pressure sensor, and a light in the bottom of the brush handle that illuminates if you're overdoing it, but we found the Sonicare much less sensitive to changes in pressure. You had to press really quite hard before the brush illuminated and vibrated as a warning. There's also no alert if you're not pressing hard enough. The iO3 and 4 are the main exceptions though. No case comes supplied with the standard model. But there are variants where this is supplied. This system is driven by the built-in rechargeable lithium-ion battery. The iO timer memorizes the elapsed brushing time, no matter if the handle is briefly turned off during brushing.For example, the 9900’s travel case is more compact, offers USB charging and has a Type-C connector. Compare this to the larger, cheaper looking and feeling Oral-B case. And unlike Sonicare, the iO’s travel case requires a proprietary power adapter.
