Delivered as promised very promptly. It’s taken me a while to get used to the vibrations in my mouth and generally only use the sensitive setting as I find it tickles too much or the vibrations from the brush body are uncomfortable if it touches your teeth. Maybe this is the same with all sonic toothbrushes. However the results are much better than my old Oral B oscillating brush and feels much much cleaner. I’m getting the hang now of avoiding the brush plastic touching my teeth so I’m happy to continue with it. One thing I’d like is a travel case but this is not offered on the site for this model. I emailed a few days ago to ask but no reply yet?
