If you were to take this with you on holiday in Europe, you would need a plug adapter, but not a voltage adapter. At the 30 second intervals, the brush will provide an audible warning via a slight pause in the brush motor. This is your cue to change from one quadrant to another. Once the 2 minutes are up 3 brief pauses in the brush motor will be heard and felt. This is your cue that the clean is over. In all honesty, for many of us we don’t need this because we are often at home and the charging stand is the natural place to leave the brush when not in use, thus the battery is constantly topped up. Whilst there is nothing particularly bad with an NiMH battery, Lithium-Ion (Li-Ion) tends to be more common and popular now.

Just be aware that bristles really only need to skim the teeth. Only a little brushing force is needed. More scrubbing pressure does not equal a better clean. The brush head supplied will depend on the variant selected, but it is one of a number of different brush head styles available from Oral-B. The Pro 1 680’s handle is water resistant. This means a rinse under the tap, or even used in the shower should be fine. Just make sure you don’t fully immerse the brush in water.

I really like the clean the brush offers, I have little in the way of complaint here. My teeth and gums felt clean after every use. It does the job it needs to do fairly well and considering what you get for the price it is without doubt a good option for many people. A small but noteworthy point is that the motor in the Pro 2 series is a little more powerful. What this means is that the head moves a bit more during each clean. It could help produce better results in the long term, but honestly it does not make a significant difference, you still get a great clean from the 680.

Battery life isn’t up there with some Sonicare models – you’re looking at a recharge roughly every three weeks – but if you want the latest and greatest toothbrush tech for less, there’s no better buy. It is the same shape and materials of the handles found on the more premium Pro 2, Pro 3, Smart 4 and Smart 5 models.

To assess battery life, we leave the toothbrush running while standing up and time how long it takes for the battery to run down. We then divide this figure by the four minutes per day brushing recommended by dentists to get an accurate idea of how many days and weeks a single charge should last. The toothbrush will stand up on a countertop, even though the base of it has a recess into which the prong on the inductive charging stand fits.
