Again better

Since 1965, I clean my teeth with electric toothbrushes. The first was for direct connection to the mains and therefore always caused this "loaded" brush in the mouth discomfort. After that many rechargeable brushes, of Blendax and Oral that I've found all quite good. But this is now even a very large number better. I've been on the lower incisors always much tartar, which is also colored by the strong tea consumption. This is now the first brush, the already reduced after a few days the strong discolorations, leaving a smooth surface on the back of the teeth.
The brush itself makes a good impression and high is perhaps the first brush, which is waterproof. All other brushes were leaky after some time on the rotating axis. This brush has no axis of rotation and therefore has a good chance that it remains sealed. The thin handle is unfortunately around and you have little control how to keep them in hand. I would like to see a less round handle, which would enable a more defined stance of the brush. Still highly recommended.
