I absolutely love this toothbrush. I'm more of a stiff bristles person because I think they get the job done better than the soft, flimsy bristles. I started using Reach toothbrushes when I was in junior high and now I'm 20 and still use them! They're a great product for people who don't like "extra soft" bristles. I do not have sensitive teeth so I'm not sure how they would be with someone who does. However, every time I get a cleaning at the dentist, they always compliment on how well I'm brushing my teeth. Love this product!!
