More shine for your pound

This is a reliable, no-nonsense electric toothbrush that does exactly what it says on the tin. It is perfect for folks who want a dentist-level clean without the smartphone integration, though be mindful that the proprietary brush heads can be a bit pricier than generic ones.

Built to work, not to show off

I have seen plenty of fancy gadgets come and go in my time, but a toothbrush needs to do one job well: clean your teeth. The Oral-B iO3 skips the gimmicky smartphone apps and fancy screens that seem to plague modern bathroom tech, focusing instead on the actual mechanics of brushing. It uses a round head that feels like it was designed by someone who actually visits a dentist, reaching those awkward gaps at the back of your mouth where manual brushes usually just wave hello.
The build quality feels sturdy, which is a breath of fresh air in a world of plastic disposables. It is not going to win any beauty pageants, but it sits comfortably in the hand and holds a charge for a good long while. If you are tired of charging your toothbrush every other day, you will appreciate this bit of German engineering.

Sensible features that actually matter

The star of the show here is the pressure sensor. It glows green when you are doing it right and red when you are being a bit too heavy-handed. It is a simple, effective way to stop you from scrubbing your gums into oblivion. You also get a two-minute timer, which is the only real instruction you need to get the job done properly.
With three cleaning modes, you have just enough variety without feeling like you are flying an airplane. It is straightforward, practical, and it gets the job done. Just remember that it comes with a 2-pin plug, so make sure your bathroom outlet is up to the task before you get excited.

The final word from the workshop

If you are looking to upgrade from a manual brush and want something reliable that won't require a degree in computer science to operate, this is your winner. At its current discounted price, it is an absolute steal for the quality you are getting. However, if you are the type who insists on cheap, generic replacement heads, you might want to look elsewhere, as this model demands its own specific refills.
