Not up to my expectations

I bought it after reading the reviews here and a positive test on DigitalVersus, I expected a lot from this BDE but after several weeks of use I do not notice any difference with manual brushing. I do not feel my mouth cleaner after use. The toothbrush stops after 2 minutes, it's annoying. We need to relight if we want to continue brushing, and 2 minutes it goes very quickly. In short, I regret this purchase, I might be to opt for a rotating and non sonic BDE.
