Oral-B iO Gentle Care White (6 units)

Despite using the brush attachment on my Io7 according to the instructions, the bristles discolor within a few days and become wider. I wonder if they'll continue to provide good, smooth results for three months.

I read a review on another site that the brushes seemed to be counterfeit, so I ordered from a reliable Coolblue site. After the usual fast delivery, I immediately replaced the brush. After the first brushing, it seemed less thorough than the older brush after the first use. Now, a week later, the brush already seems worn out... a shame, because I've been recommending the Oral B toothbrush for years. For that price, you'd expect a product that's worth the money.

In the beginning I had to get used to the brush head, which I was allowed to test. The bristles are a bit softer than those of a regular electric toothbrush, so I thought it might clean a little less. But I have the feeling that I can achieve everything much better through the hair. Last week I had to use the old toothbrush again, because I had to charge the new one. How hard the hair felt!

Other than that, it's a nice, good brush head.

One downside: it has to be replaced every three months. That's a bit expensive every time.
