The others are: Braun Oral-B CrossAction PRO 600, which I have rated four stars, as well as the Oral-B PRO 6200 Electric Toothbrush with Premium free SmartGuide and Bluetooth which could bring her only 3 stars in my opinion, unnecessary and expensive gadgetry. I like the Oral-B TriZone 750 Black already better by design - the matt black rubber coating is not only good in the hand but evaluates the appearance clearly on. Then I like the slightly larger brush heads with itself Floating bristles, much better than the small, round oscillating heads of the other two. That is certainly very individual, and it may here be different preferences; nevertheless brushing just for switching from traditional manual toothbrushes with TriZone capita is easier, because the old plaster movement can be easily maintained, and make the side moving the bristles just as thorough in cleaning by hand. Furthermore I have done in the first few dental cleanings with the round CrossAction heads pain on my teeth while I did not feel the TriZone uncomfortable. Nice side effect is that I clearly less toothpaste spittle runs respectively when using the TriZone from the mouth than in the smaller, round heads of Cross Action. With whom I drool uncontrollably perfectly what brings regularly ugly white stains on clothing. Why this is so, but does not open up to me. From the technical resources, I like the TriZone 750 Black also prefer, for it has in addition to the Timer (30 seconds for each quadrant and stuttering after two minutes brushing time), the also both other devices in addition a warning indicator for low battery, the I miss in the PRO 600. While the PRO 6200 provides a more accurate indication of the charge state, but I can despite their gadgets not inspire quite, especially since these partially superfluous gimmicks must be paid for dearly. All three have in common that they bring a tangible result in more thorough cleaning as compared to a conventional manual toothbrush; However, my favorite is clearly the TriZone 750 Black.
