I’ve bought this toothoth to replace my oral-b Io 3 toothbrush. It’s amazing. My dentist will be pleased with me. Since using my oral-b 3 toothbrush I’ve never been to see the hygienist and my dentist says I would put her out of a job as my teeth a very clean no decay. With my Oral B io 10 I’m brushing my teeth better with using the app. I’m usually all done by about 3 mins. With the app the teeth Cinders · very.co.uk

This is the third Waterpik brush/floss I have purchased. The first one for myself, then one for my cousin, then the third one again for me because my first one stopped working after 4 years. I love this product and do not see myself without it. I am shocked that other companies have not followed suit in creating this type of brush/floss all-in-one toothbrush.
