Our choice: Oral-B Pro 3 3500<\/h2>\n\n\n\n

The Pro 3 features a more user-friendly pressure sensor and is the cheaper option. It cleans the teeth just as well as the iO2. <\/p>\n\n\n\n

Brush heads for the iO2 are about twice the price of those for the Pro 3. This makes a big difference over several years of ownership.<\/p>\n\n\n\n

In recent times the Pro 300 availability hasn't been as good and it feels as though it may soon be discontinued. This has meant that on occasion the price has been higher than we would expect.<\/p>\n\n\n\n

But if you can pick a variant of the Pro 3 up for less than \u00a340, it is still a bargain. We tend to find that the Pro 3 3500, which is the same as the 3000 but comes with a travel case, actually tends to be cheapest.<\/p>\n\n\n

When to choose the iO2<\/h2>\n\n\n\n

The main reasons to choose the iO2 over the Pro 3 would be if you prefer the design of the iO range, or if you would benefit from a brush with a long battery life.<\/p>\n\n\n\n

The iO2 has the best battery life of any Oral-B brush I've used. In testing it lasted 37 days, whereas the Pro 3 lasted 20 days, which still isn't bad overall. Unless you don't have the means to charge your brush frequently, it's not worth paying too much attention to.<\/p>\n\n\n
