duet really extremely cheap!

Actually, I wanted to just make a comparison, because I discovered this duo and convinced me immediately:
For a family that is at times also when traveling, just great!
While a toothbrush is charging, the other can be used or taken already times. The battery lasts but a few days without recharging!

Otherwise usual Oral-B quality!
Had indeed a limiting design of Pro 650 very unlucky (the rubber stretched over a large part of the handpiece and dissolved sticky on, .... !!!), but convinced them kept simple toothbrush again! The rubber piece on the switch feels durable.
Otherwise: thorough cleaning of the teeth is, comfortably in your hand and is easy to clean.
Well I also like the solution with the Metallringlein the neck of the toothbrush neck. Finally, this part is easier to clean, without any toothpaste remains lost so persistent in the groove!
