Amazing really pleased does the job well. Easy to use. I like the light as it shows your using it correctly.
My dentist recommended a new toothbrush to help with my gum disease. I have had the basic Oral b brushes but this one really helps with knowing the pressure exerted and to keep track of my routine.
I have ultra sensitive teeth and have never been able to tolerate an electric toothbrush before. Encouraged by my dentist and hygienist I have purchased an Oral B io4 So far so good, I am using it with increased confidence. A lovely product, easy to manage and clear information on correct use.
