The initial idea was a "Ultrasonic Toothbrush". Investigations revealed however that one often succumbs 1. a mistake and should actually speak of "sonic toothbrushes" and 2. it is a quasi only provider of real "ultrasound toothbrushes" and the reviews are not a true recommendation for the product.
A review of the reviews of sonic toothbrushes of the most famous manufacturers lies for me then just choosing a Braun. Everything else is either more expensive or even fraught with problems, or both.
Convinced then have us ultimately reports to the Braun Pulsonic-not.
We have therefore re-elected with this brush rotation toothbrush.
The fact that this also makes 40,000 pulsations, led me to believe that a sonic toothbrush in principle is otherwise well. But you'll forgive my ignorance.
Another argument fpr us was that you can also use the Trident essays and thus everyone, depending on your mood, you can brush by rotating or classically large head.
We have the brush for several weeks now in use and I can so far nothing negative.
The battery lasts about as indicated.
The cleaning result is, though not by factors, better than our age-old brush. But as I said. Clean and smooth, the teeth were with the old brush already.
A selling point for us was in any case the two handpieces, especially since we have paid little more than the standard range with a handle. We expect to be able to double the life of the product in order (one reported so short-lived batteries), by "storing" the second handpiece and undergo only now and then a refresh charging.
So I forgive "only" 4 stars because the plaster has not improved to the same extent as the purchase price has increased (compared to our old brush).
