I looked around a lot before deciding to get this model toothbrush. I finally decided on the Triumph 9400 because I found a good price for it. I wasn't dissapointed at all. My teeth feel really clean and it feels like a good dental cleaning. One thing I really like about it is that I don't have to use the sensative tooth toothpaste anymore. I've used it for about a month and my teeth are feeling a lot less sensative than they used to be.
The charge lasts really well and I like the display. One thing I don't care for is that I don't really know what kind of toothpaste I am supposed to use with the polishing head since the directions don't tell you.
Overall I definitely recommend it.
