As noted above, the Quip micro-vibrations barely remove any plaque. However, sometimes the brush head and bristle design can make up for the insufficient electric power vibrations when you brush manually in addition to the vibrations.
On a separate day, I test for Quip's total plaque-removing capability by staining my plaque pink and seeing how much it removes. The images in this section are the test results but can also be seen in the video accompanying this article. Once again, the photos show awful results. A lot of plaque is left behind, especially between the teeth. What makes a toothbrush good or even great is how far between the teeth it removes plaque. The Quip Toothbrush removes plaque from the most exposed surfaces of the teeth while it completely misses between them. Even a towel or the cheapest toothbrushes will remove plaque from exposed surfaces of teeth.
In my opinion, the reason for this poor performance is an inferior brush head design. The bristles seem very stiff, which is a problem for two reasons. First, it doesn’t allow bristles to reach far between the teeth. Second, stiff bristles can wear down gums and teeth, causing gum recession, thin enamel, and notches in the tooth root.
Not only do I not recommend the Quip toothbrush, but I also recommend almost every other toothbrush over it. In addition to the Quip toothbrush review, I don’t recommend any micro-vibration toothbrush, but virtually all the other brushes still outperform the Quip because they have better brush heads.
