“I've already left a review just after I purchased it but here goes. I started off with the sensitive setting which was very good apart from keeping up with the built in timer, I had to add another 30 second cycle to finish off. Now though, I have moved on to the clean setting and I can now keep up with the timer. You can feel the difference between the two settings as it cleans better. The initial tickling sensation has now gone now I'm used to it, however, because of how it's designed you get a lot of foaming so clean your teeth before you get dressed.”
