For me brushing my teeth is a very enjoyable event in my life I know it sounds different but my cousin is a dentist and she has drilled this into my life and yes now that I am older I understand the importance of having your own teeth.
The replacement heads on my toothbrush don’t look any different but the sounds are a little louder with this new brush head. Not very noticeable but I can hear a humming.
Does a very nice job in making the teeth clean and I usually brush twice a day so it took a few brushing before I noticed the humming. The brushes look the same and setup with removing one out and the other one in is the same.
So for me will give this 4 stars and not 5 because of the slight humming in the exchange.
