Review (5/5): Not sure if it is working properly?
This is my 3rd Oral B toothbrush and this is the first one that seems to "hiccup" while in use. The power seems to pulsate? I'm not quite sure how to explain it but I do think this is a defect. It does get my teeth clean but the power seems to hesitate while I am using it, which is very annoying. It's not a question of being charged, it is fully charged.
Thanks to the comments of another reviewer, I realize this was my mistake so I am changing my rating to 5 stars. At first I found the "hiccup" annoying, but I am used to it now.
