To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Fast delivery. Great value but could be a bit cheaper looking at the fact that it is a piece of plastic + it also doesn‘t last as long as the stated 3 months. They still do their work though and it really feels like my teeth are clean.
Oral-B products are very good. Including these brush heads they clean very well so much better than a manual toothbrush. The negative is they can't be recycled as far as I know. So millions of these in land fill which take a long time to break down. But the same for a manual toothbrush.
Well that's obvious, you might say, but not really. There are plenty of tooth brushes on the market that don't do a very good job at what they are designed to do. These however, do a great job. I have taken off a star because of the cost. They are outrageously expensive.
