That's not an issue once you've set it to your exact preferences, though; provided you don't like to switch modes on the fly, it's a superb brush. The orange/red panel will be lit red when activated, making it very clear when you are applying too much pressure. It’s a nicely balanced brush, easy to grip, and with a head that’s easy to get into the tightest corners of the mouth. However, each replacement will last at least three months, as the brush isn't particularly power-hungry.

Once done, the Series 10's bright color display will rate your brushing, and show the battery life remaining on the brush. Once you had a electric toothbrush you soon will know how long to brush your teeth and when to change the brush head. its biggest downside is the need to replace batteries, along with brush heads, every few months, which isn't particularly eco-friendly nor cost-effective in the long run. The Ordo Sonic+ works on the same principle as Philips Sonicare electric toothbrushes, sending rapid pulses of water between teeth to dislodge sticky plaque, but in our tests we found it delivered a more gentle clean – something helped further by its soft bristles, which help avoid damage to your gums. The Philips Sonicare 9900 Prestige is another impressive electric toothbrush designed to improve your technique long-term by monitoring your brushing and giving real-time feedback.A 2 pin power adapter is hardwired into it, which is suitable for 2 pin shaver sockets the adapter supports 220-240v. This is different from the 4 zone (quadrant), 30 second pacing the brush uses when not being used in real-time with the app. That could be extremely useful if you're concerned that you're missing spots (something that your dentist may have pointed out), but it adds to the cost. You get the same low-friction magnetic motor, simple controls, crisp LCD display, and Bluetooth connectivity.

You can switch between the five modes – Daily Clean, Sensitive, Whiten, Gum Care and Intense – by pressing the lower button.As an oscillating and rotating brush, it does still feel different in use to a sonic toothbrush, it doesn’t feel as light and gentle as they often do. It also offers a real-time coaching mode, and it’s this feature that the cheaper iO Series 4 doesn’t have.
